Suppose that the material to be used in a fuse melts when the current density rises to 459 A/cm2. What diameter of cylindrical wire should be used to limit the current to 0.53 A?
Answers
Answer:
The required diameter of the fuse wire should be 0.0383 cm to limit the current to 0.53 A with current density of 459 A/cm² .
Explanation:
We are given current density of 459 A/cm² and we want to limit the current to 0.53 A in a fuse wire. We are asked to find the corresponding diameter of the fuse wire.
Recall that current density is given by
j = I/A
where I is the current flowing through the wire and A is the area of the wire
A = πr²
but r = d/2 so
A = π(d/2)²
A = πd²/4
so the equation of current density becomes
j = I/πd²/4
j = 4I/πd²
Re-arrange the equation for d
d² = 4I/jπ
d = √4I/jπ
d = √(4*0.53)/(459π)
d = 0.0383 cm
Therefore, the required diameter of the fuse wire should be 0.0383 cm to limit the current to 0.53 A with current density of 459 A/cm² .
Answer:
diameter is 1 cm
Explanation:
diameter is 1 cm

b) Determine the degree of saturation (S), void ratio (e), porosity (n), and water content (ω) for the soil as it existed in its natural state.
c) Determine the volume of water required to saturate 1 ft3 of soil in its natural state.
Answers
In this problem, we are given the weight of soil in its natural state and after being dried, as well as the specific gravity of the soil. From this information, we can determine various properties such as degree of saturation, void ratio, porosity, and water content.
Additionally, we can calculate the volume of water required to saturate the soil in its natural state.
a) In the phase diagram, we have:
Wt (total weight) = 113 lbs
Ww (weight of water) = 113 - 96 = 17 lbs
Ws (weight of solids) = 96 lbs
Vt (total volume) = Vv (volume of voids) + Vs (volume of solids)
Vv is the volume of water, and Vs is the volume of solids.
We need additional information to determine the values of Vv and Vs.
b) To determine the degree of saturation (S), we use the equation:
S = (Ww / Ws) * 100
Substituting the given values, we can calculate the degree of saturation.
The void ratio (e) is the ratio of the volume of voids to the volume of solids. It can be calculated as:
e = Vv / Vs
The porosity (n) is the ratio of the volume of voids to the total volume. It can be calculated as:
n = Vv / Vt
The water content (ω) is the ratio of the weight of water to the weight of solids. It can be calculated as:
ω = (Ww / Ws) * 100
Using the given information, we can calculate the values of S, e, n, and ω.
c) The volume of water required to saturate 1 ft3 of soil in its natural state can be determined by multiplying the volume of voids (Vv) by the specific gravity (Gs) of the soil. Since the specific gravity is given as 2.70, we can calculate the volume of water required.
By applying the relevant equations and using the given information, we can determine the desired properties and volume of water required for the soil in its natural state.

One benefit for using self-consolidating concrete is __________________________________. A. Lower plastic shrinkage cracking B. Reduced tensile creep C. Its ability to be placed in congested spaces D. A low viscosity achieved using high water contents and superplasticizers
Answers
One benefit of using self-consolidating concrete is its ability to be placed in congested spaces, allowing for easier and more efficient construction.
Self-consolidating concrete (SCC) is a specialized type of concrete that has the ability to flow and fill complex and congested spaces without the need for external vibration or compaction. This unique property of SCC offers several advantages in construction projects.
One major benefit of using SCC is its ability to be placed in congested spaces. Traditional concrete often requires manual compaction or vibration to ensure proper consolidation and filling of formwork, which can be challenging in tight or intricate areas. SCC eliminates the need for these time-consuming and labor-intensive processes, making it easier and more efficient to place concrete in complex structures or congested spaces.
By using SCC, construction teams can save time and effort in placing concrete, resulting in improved productivity and reduced labor costs. Additionally, the elimination of external vibration or compaction reduces noise and vibration levels at the construction site, contributing to a more comfortable and safer working environment.
In summary, the ability of self-consolidating concrete to be placed in congested spaces simplifies construction processes, enhances productivity, and improves overall construction efficiency.

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

how does the function of a generator relate to the function of a motor
Answers
The function of a generator and the function of a motor are closely related as they both involve the conversion of energy.
A generator is a device that converts mechanical energy into electrical energy. It operates by utilizing the principle of electromagnetic induction. When a generator is driven by a mechanical power source, such as an engine or turbine, it spins a rotor within a magnetic field. This rotation induces an electromotive force (EMF) in the conductors of the rotor, generating electrical energy. In other words, a generator converts mechanical energy into electrical energy.
On the other hand, a motor performs the opposite function. It converts electrical energy into mechanical energy. Motors use the phenomenon of electromagnetic induction as well, but in reverse. When a current is applied to the conductors of a motor's rotor within a magnetic field, it experiences a force that causes the rotor to rotate. This rotational motion is then used to drive the mechanical load connected to the motor. In summary, a motor converts electrical energy into mechanical energy.
In essence, generators and motors are complementary devices that operate using similar principles of electromagnetic induction. While generators produce electrical energy from mechanical energy, motors utilize electrical energy to generate mechanical motion. The ability to convert energy between electrical and mechanical forms is crucial in various applications, ranging from power generation to industrial machinery and transportation systems.

Explanation:
for a uniform-diameter shaft, does hollowing the shaft increase or decrease the critical speed? determine the ratio of the critical speeds for a solid shaft of diameter d to a hollow shaft of inner diameter d/2 and outer diameter d.
Answers
Hollowing out a uniform-diameter shaft increases its critical speed. The ratio of the critical speeds of a solid shaft of diameter d to a hollow shaft of inner diameter d/2 and outer diameter d is approximately 0.83.
When the diameter of a solid shaft is reduced by hollowing it out, the mass of the shaft decreases, and as a result, the critical speed increases. The reduction in mass means that the shaft is less likely to vibrate uncontrollably at high speeds.
The critical speed of a solid shaft of diameter d can be calculated using the formula: N = \((k * (E / rho)) ^ 0.5 * (d / L) ^ 0.5\), where N is the critical speed, k is a constant that depends on the end support conditions, E is the modulus of elasticity, rho is the density of the material, d is the diameter of the shaft, and L is the length of the shaft.
For a hollow shaft of inner diameter d/2 and outer diameter d, the formula for the critical speed becomes:
N = \((k * (E / rho)) ^ 0.5 * ((d/2)^2 + (d/2)^2) / L) ^ 0.5\)
Simplifying the formula, we get:
N =\((k * (E / rho)) ^ 0.5 * (d / L) * 0.707\)
Therefore, the ratio of the critical speeds of a solid shaft of diameter d to a hollow shaft of inner diameter d/2 and outer diameter d can be expressed as:
N_solid / N_hollow = \(((k * (E / rho)) ^ 0.5 * (d / L) ^ 0.5) / ((k * (E / rho)) ^ 0.5 * (d / L) * 0.707) = (d / (2 * d / sqrt(2))) ^ 0.5 = 0.83\)

Consider filling a cylinder of compressed argon from a high- pressure supply line as shown below. Before filling, the cylinder contains 10 bar of argon at room temperature. The valve is then opened, exposing the tank to a 50 bar line at room temperature un- til the pressure of the cylinder reaches 50 bar. The valve is then closed. For argon take cP = (5/2)R and the molecular weight to be 40 g mol. You may use the ideal gas model. (a) What is the temperature right after the valve is closed? (b) If the cylinder sits in storage for a long time, how much heat is transferred (in kJ/kg)? (c) What is the pressure of the cylinder when it is shipped (after it was stored for a long time)?
Answers
The initial pressure in the cylinder of 10 bar of argon with \(C_p\) = (5/2)·R
and the added gas at pressure of 50 bar gives the following values.
(a) 400.6 K
(b) 51.184 J
(c) The pressure of the cylinder when it is shipped is 37.194 bar
How can the temperature, heat transferred and pressure be calculated?(a) Adiabatic compression, we have;
\(\dfrac{p_{1}}{p_{2}} = \mathbf{\left (\dfrac{T_{_{1}}}{T_{2}} \right )^{\dfrac{k}{k-1}}}\)
Where;
\(k = \dfrac{C_p}{C_v} = \mathbf{\dfrac{C_p}{C_p - R}}\)
Therefore;
\(K= \mathbf{\dfrac{\frac{5}{2} \cdot R}{\frac{5}{2} \cdot R - R} }= \dfrac{5}{3}\)
Which gives;
\(\dfrac{10}{50} = \left (\dfrac{298}{T_{2}} \right )^{\dfrac{\frac{5}{3} }{\frac{5}{3} -1}} = \left (\dfrac{298}{T_{2}} \right )^{2.5}\)
\(\dfrac{50}{10} = \mathbf{ \left (\dfrac{T_2}{298.15} \right )^{2.5}}\)
\(ln(5)= 2.5\cdot ln\left (\dfrac{T_2}{298.15} \right )\)
\(T_2 = 298 \times e^{\dfrac{ln(5)}{2.5} } \approx \mathbf{567.29\, K}\)
The temperature
Using an ideal gas model, we have;
\(\dfrac{V_{1}}{V_{2}} = \mathbf{\dfrac{P_{2}\times T_{1}}{T_{2} \times P_1}}\)
Which gives;
\(\dfrac{V_{1}}{V_{2}} = \dfrac{50\times 298}{567.29 \times 10} \approx 2.625\)
V₁ = 2.625·V₂
Volume occupied by the gas in the cylinder after the pressure increases is therefore;
\(V_2 = \dfrac{V_1}{2.625} \approx 0.381 \cdot V_1\)
Volume of gas added is therefore;
\(V =V_1 - \dfrac{V_1}{2.625} = 0.619\cdot V_1\)
Considering a molar volume of gas, we have;
0.040 × 0.619 × 2.5×8.3145×(T₃ - 298) = 0.040 × 0.381 × 2.5×8.3145×(567.29 - T₃)
Solving gives;
T₃ ≈ 400.6 K
For a molar volume of gas cylinder, the temperature just after the valve is closed is T₃ ≈ 400.6 K
(b) If the cylinder sits in the storage for a long time, and heat is conducted out, we have;
The temperature of the cylinder will revert to room temperature of 298 K
The heat transferred is therefore;
0.040 × (2.5 × 8.3145 - 8.3145) ×(400.6 - 298) ≈ 51.184
The heat transferred from the cylinder is 51.184 J
(c) The pressure of the gas in the cylinder is therefore;
\(\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}\)
Which gives;
\(P_2= \mathbf{\dfrac{P_1}{T_1} \times T_2}\)
Therefore;
\(P_2= \dfrac{50}{400.6} \times 298 \approx 37.194\)
The pressure of the cylinder when it is shipped is 37.194 bar

Answers
The magnitude of the line voltage at the source end of the line is 4168 volts.
To find the magnitude of the line voltage at the source end of the line, we can use the power factor of the first load, which is cos(ϕ) = 630/900 = 0.7. The total reactive power of the load is Q = 840 kvar, and the apparent power is S = 900 kVA.
Therefore, the reactive power of the load is Q = S sin(ϕ) = 900 sin(arccos(0.7)) = 610 kvar. The total reactive power of both loads is 610 + 840 = 1450 kvar. Using the power formula, we get P = √3 V L I L cos(ϕ) => V L = P / (√3 I L cos(ϕ)), where I L = S / (√3 V L), and P = 630 kW.
By solving these equations, we get V L = 4168 volts.

of rod B.
c) Find the magnitude of the impulse for the condition in part b. (3 marks)
d) Find the percent decrease in kinetic energy which corresponds to the impact in
part b.
Answers
Answer:
a) \(V_A = \frac{(M_A - eM_B)U_A + M_BU_B(1+e)}{M_A + M_B}\)
\(V_B = \frac{M_AU_A(1+e) + (M_B - eM_A)U_B}{M_A + M_B}\)
b) \(U_A = 3.66 m/s\)
\(V_B = 4.32 m/s\)
c) Impulse = 0 kg m/s²
d) percent decrease in kinetic energy = 47.85%
Explanation:
Let \(U_A\) be the initial velocity of rod A
Let \(U_B\) be the initial velocity of rod B
Let \(V_A\) be the final velocity of rod A
Let \(V_B\) be the final velocity of rod B
Using the principle of conservation of momentum:
\(M_AU_A + M_BU_B = M_AV_A + M_BV_B\)............(1)
Coefficient of restitution, \(e = \frac{V_B - V_A}{U_A - U_B}\)
\(V_A = V_B - e(U_A - U_B)\)........................(2)
Substitute equation (2) into equation (1)
\(M_AU_A + M_BU_B = M_A(V_B - e(U_A - U_B)) + M_BV_B\)..............(3)
Solving for \(V_B\) in equation (3) above:
\(V_B = \frac{M_AU_A(1+e) + (M_B - eM_A)U_B}{M_A + M_B}\)....................(4)
From equation (2):
\(V_B = V_A + e(U_A -U_B)\)......(5)
Substitute equation (5) into (1)
\(M_AU_A + M_BU_B = M_AV_A + M_B(V_A + e(U_A -U_B))\)..........(6)
Solving for \(V_A\) in equation (6) above:
\(V_A = \frac{(M_A - eM_B)U_A + M_BU_B(1+e)}{M_A + M_B}\).........(7)
b)
\(M_A = 2 kg\\M_B = 1 kg\\U_B = -3 m/s( negative x-axis)\\e = 0.65\\U_A = ?\)
Rod A is said to be at rest after the impact, \(V_A = 0 m/s\)
Substitute these parameters into equation (7)
\(0 = \frac{(2 - 0.65*1)U_A - (1*3)(1+0.65)}{2+1}\\U_A = 3.66 m/s\)
To calculate the final velocity, \(V_B\), substitute the given parameters into (4):
\(V_B = \frac{(2*3.66)(1+0.65) - (1 - (0.65*2))*3}{2+1}\\V_B = 4.32 m/s\)
c) Impulse, \(I = M_AV_A + M_BV_B - (M_AU_A + M_BU_B)\)
\(I = (2*0) + (1*4.32) - ((2*3.66) + (1*-3))\)
I = 0 \(kg m/s^2\)
d) %\(\triangle KE = \frac{(0.5 M_A V_A^2 + 0.5 M_B V_B^2) - ( 0.5 M_A U_A^2 + 0.5 M_B U_B^2)}{0.5 M_A U_A^2 + 0.5 M_B U_B^2} * 100\%\)
%\(\triangle KE = \frac{((0.5*2*0) + (0.5 *1*4.32^2)) - ( (0.5 *2*3.66^2) + 0.5*1*(-3)^2))}{ (0.5 *2*3.66^2) + 0.5*1*(-3)^2)} * 100\%\)
% \(\triangle KE = -47.85 \%\)
What are the 3 types of irony and examples?.
Answers
The three types of irony are Verbal Irony, Situational Irony, and Dramatic Irony.
Example of Verbal Irony:
When a statement's intended meaning differs from what is actually said, it is said to be verbally ironic.In Shrek, Donkey asks Shrek if he can stay with him. Shrek replies, "Of course," when he really means, "No, not really."Example of Situational Irony:
Situational irony occurs when a situation's conclusion is completely unanticipated. For instance, everyone in Emerald City believes that Oz is strong and impressive in the book The Wonderful Wizard of Oz. Oz, however, turns out to be the exact opposite—an aged guy devoid of any supernatural abilities.Example of Dramatic Irony:
Dramatic irony occurs when characters are unaware of information that the audience is aware of.When the readers are aware that a deadly shark is present in the water but the carefree beachgoers are unaware that they are being pursued.What is Irony?
When something unexpected occurs, it is ironic. The thing opposite to what we anticipate usually occurs, and this is either humorous or dramatic.

A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [100] direction. If the critical resolved shear stress for this material is 1.98 MPa, calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the direction.
Answers
Answer:
the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa
Explanation:
From the given information;
To determine the angle \(\phi\) between the direction [100] and [111]; we have:
\(\phi = cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)
where;
[u₁,v₁,w₁] and [u₂, v₂, w₂] are directional indices.
replacing 1 for u₁ , 0 for v₁ and 0 for w₁ ;
also replacing 1 for u₂, 1 for v₂ and 1 for w₂ ; we have :
\(\phi = cos ^{-1} [\dfrac{1*1+0*1+0*1}{ \sqrt{(1^2+0^2+0^2) (1^2+1^2+1^2) }}}\)
\(\phi = 54.7^0\)
To determine the angle \(\lambda\) for the slip direction \([1 0 \overline 1]\)
\(\lambda= cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)
replacing 1 for u₁ , 0 for v₁ and 0 for w₁ ;
also replacing 1 for u₂, 1 for v₂ and -1 for w₂ ; we have :
\(\lambda = cos ^{-1} [\dfrac{1*1+0*0+(0*-1)}{ \sqrt{(1^2+0^2+0^2) (1^2+0^2+(-1^2)) }}}\)
\(\phi = cos ^{-1} [\dfrac{1}{\sqrt{2}}]\)
\(\lambda = 45^0\)
The yield strength for the slip process \([1 0 \overline 1]\) can now be calculated as:
\(\sigma_x = \dfrac{t_{xr}}{cos \phi \ \ cos \lambda}\)
where
\(t_{xr}\) = 1.98 MPa
\(\sigma_x = \dfrac{1.98}{cos 54.7^0 \ \ cos 45}\)
\(\sigma_x = \dfrac{1.98}{0.5779 *0.7071}\)
\(\mathbf{\sigma _x = 4.85 \ MPa}\)
Hence, the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa
a runway identified as runway 27 serves operations oriented to which approximate direction?
Answers
A runway identified as runway 27 serves operations oriented to the westward direction.
What are runways?
A runway is defined as an airport's paved surface. A runway is used for aircraft takeoff and landing operations. The most important runway, without a doubt, is the primary runway, which is the longest runway that has lighting and instrument landing aids. Runways are usually numbered based on their compass bearings, and they are designated L or R if two runways are close together but not parallel. It's worth noting that the numbers don't signify the degree to which the runway is off of a north-south heading, but rather the runway's magnetic bearing.
How to identify the approximate direction of operations from the runway designation?
A runway identified as runway 27 serves operations oriented to the westward direction. The runway numbering system is used to determine the runway direction, which is based on its magnetic direction from 0 to 359 degrees. These numbers are used to designate runway headings in tens, as well as for headings within ten degrees. Runway 27 would be the one with the magnetic heading of approximately 270 degrees (270-279). As a result, an aircraft taking off or landing on runway 27 would travel in an approximately westward direction.
