The eccentricity "e" of a prestressed members can best be described as:

Answers

Answer 1

The eccentricity "e" of a prestressed member refers to the distance between the centroid (geometric center) of the member and the line of action of the prestressing force. In other words, it is the measure of how off-center the force is applied to the member.

The eccentricity can have a significant effect on the behavior and strength of the member. For example, if the eccentricity is too large, it can cause bending and shear forces that may exceed the design capacity of the member. Additionally, the amount of prestress force that can be applied may be limited by the eccentricity. Therefore, in the design of prestressed members, the eccentricity must be carefully considered and controlled. Engineers must ensure that the eccentricity is within the acceptable range and that the member can withstand the expected loads and stresses. This may involve using different types of prestressing systems, adjusting the geometry of the member, or incorporating additional reinforcement. In summary, the eccentricity of a prestressed member is a critical factor in its design and behavior. It refers to the distance between the centroid and the line of action of the prestressing force and must be carefully controlled to ensure the safety and performance of the structure.

Using stored liquidity to offset a deposit drain will reduce the size of the bank but using purchased liquidity to offset the drain will not. Group startsTrue or False

Answers

The given statement, "Using stored liquidity to offset a deposit drain will reduce the size of the bank but using purchased liquidity to offset the drain will not" is False.

What is liquidity?Liquidity is defined as the capacity of a company or organization to fulfill its obligations as they become due. In finance, liquidity alludes to the degree to which an asset or security can be converted to cash without affecting its market price.

For banks, it refers to their ability to meet their depositors' demand for cash without going bankrupt.What is stored liquidity?The liquidity that a bank has on hand in the form of cash and other assets is referred to as stored liquidity. It is included in the bank's balance sheet.

What is purchased liquidity?Purchased liquidity is a source of funds that a bank acquires from other sources such as the central bank, other banks, or the financial market.In this regard, both purchased and stored liquidity are means of offsetting deposit drains.

In the case of purchased liquidity, banks may acquire liquidity by borrowing from the central bank, other banks, or the financial market when the demand for cash exceeds the available stored liquidity.On the other hand, stored liquidity is already available to the bank and does not need to be borrowed.

In reality, the usage of purchased liquidity, rather than stored liquidity, may increase the size of the bank to account for the increased amount of liquidity, especially if they need to borrow more than their stored liquidity can offer.

In conclusion, the statement that "Using stored liquidity to offset a deposit drain will reduce the size of the bank but using purchased liquidity to offset the drain will not" is false because the usage of purchased liquidity, rather than stored liquidity, may increase the size of the bank to account for the increased amount of liquidity.

Answers

Split-phase motors are induction motors used in applications that operate in the fractional horsepower range, such as fans and compressors in capillary tube systems.

Another name for the split phase motor is the resistance start motor. It contains a single cage rotor and two windings in its stator, referred to as the main winding and starting winding. The positions of both windings differ by 90 degrees. The starting winding has a high inductive reactance and a very low resistance, while the main winding has a high resistance and a low inductive reactance. With the auxiliary winding, a resistor is connected in series. The two windings' respective currents are not equal, and as a result, the rotating field is not even. As a result, the beginning torque is low, typically 1.5 to 2 times the reported running torque. Both windings are parallel connected when the motor first starts.

Answers

Answer:

the reduction in the heat gain is 2.8358 kW

Given that;

Shaft outpower of a motor  = 75 hp = ( 75 × 746 ) = 55950 W

Efficiency of motor  = 91.0% = 0.91

High Efficiency of the motor  = 95.4% = 0.954

now, we know that, efficiency of motor is defined as;  =  /

where   is the electric input given to the motor

so

=  /

we substitute

= 55950 W / 0.91

= 61483.5 W

= 61.4835 kW

now, the electric input given to the motor due to increased efficiency will be;

=  /

we substitute

= 55950 W / 0.954

= 58647.79 W

= 58.6477 kW

so the reduction of the heat gain of the room due to higher efficiency will be;

Q =  -

we substitute

Q = 61.4835 kW - 58.6477 kW

Q = 2.8358 kW

Consider 100 kg of steam initially at 20 bar and 240 degrees C as the system. Â Determine the change in exergy, in kJ, for each of the following processes:

(a) The system is heated at constant pressure until its volume doubles.

(b) The system expands isothermally until its volume doubles.



Let Tsubzero = 20 degrees C, Psubzer = 1 bar and ignore the effects of motion and gravity.

Answers

The given initial state of steam as the system are: Pressure P1 = 20 bar.

Temperature T1 = 240 °C Mass m = 100 kg. Considering the above conditions, the specific volume (v1) of the steam can be calculated as follows: For steam, specific gas constant, R = 0.4615 kJ/kg-K The molecular weight of steam, M = 18.01528 kg/kgmol. The universal gas constant, Ru = 8.314 kJ/kmol-K Specific volume of steam,v1 = Ru T1 / P1 Mv1 = 8.314 × 240 / 20 × 18.01528v1 = 0.2254 m³/kg. Now let us calculate the initial exergy of the system by using the equation

Exergy = m [u - u(ref)] + (P - P(ref)) v where u is the specific internal energy of the steam and u(ref) is the specific internal energy of the steam at reference temperature and pressure P is the pressure of the steam P(ref) is the reference pressure v is the specific volume of the steam. Exergy of the steam at reference temperature and pressure can be calculated as: u(ref) = h(ref) - Pv (ref)Where, h(ref) = enthalpy of the steam at reference temperature and pressure v(ref) = specific volume of the steam at reference temperature and pressure. From steam table, at P = 1 bar and T = 20°C, h(ref) = 2501.9 kJ/kg and v(ref) = 0.00104 m³/kg

Substituting all the given values in the equation,

Exergy1 = 100 [u1 - u(ref)] + (20 - 1) 0.2254

Exergy1 = 100 [3182.5 - 2501.9 - (20 × 0.00104)]

Exergy1 = 66949 kJ.

The change in exergy for the given processes are given below:

(a) The system is heated at constant pressure until its volume doubles. In this case, the final specific volume is v2 = 2v1 = 0.4508 m³/kg. From steam table at P = 20 bar and v = 0.4508 m³/kg, h2 = 3484.9 kJ/kg and u2 = 3019.2 kJ/kg.Using the above-mentioned equation for the second time for the new state, we haveExergy2 = 100 [u2 - u(ref)] + (20 - 1) 0.4508Exergy2 = 100 [3019.2 - 2501.9 - (20 × 0.00104)] + (20 - 1) 0.4508Exergy2 = 70603 kJThe change in exergy of the system, ΔE = Exergy2 - Exergy1 = 70603 - 66949 = 3654 kJ

(b) The system expands isothermally until its volume doubles. In this case, the pressure and temperature decrease until the final specific volume is v2 = 2v1 = 0.4508 m³/kg. Using steam table for v = 0.4508 m³/kg, T2 = 196.72°C and P2 = 6.18 bar.Now, specific internal energy and enthalpy of the steam can be calculated as:u2 = 2801.7 kJ/kg and h2 = 3208.7 kJ/kg.Exergy2 can be calculated by using the above-mentioned equation for the second time with the new values of u2, h2, v2 and P2.Exergy2 = 100 [u2 - u(ref)] + (6.18 - 1) 0.4508Exergy2 = 100 [2801.7 - 2501.9 - (6.18 × 0.00104)] + (6.18 - 1) 0.4508Exergy2 = 67821 kJ. The change in exergy of the system, ΔE = Exergy2 - Exergy1 = 67821 - 66949 = 872 kJ

Therefore, the change in exergy for the given processes are as follows:

(a) The system is heated at constant pressure until its volume doubles. The change in exergy is 3654 kJ.

(b) The system expands isothermally until its volume doubles. The change in exergy is 872 kJ.

Determine the steady rate of heat transfer through this double-pane window and the temperature of its inner surface for a day during which the room is maintained at 20°C while the temperature of the outdoors is −5°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1 = 10 W/m2⋅K and h2 = 25 W/m2⋅K, respectively, and disregard any heat transfer by radiation.

Answers

Answer:

The answer is below

Explanation:

Given:

kg (glass) = 0.78 W/m⋅K, ka (air) = 0.026 W/m⋅K, h1 = 10 W/m2⋅K, h2 = 25 W/m2⋅K, glass length = Lg = 3 mm = 0.003 m, Lo = 3 mm = 0.003 m, La = 12 mm = 0.012 Height = 1.5 m, width = 2.4 m, room temperature = T = 20°C. Therefore:

Total resistance per unit area is given as:

\(R"=\frac{1}{h_1}+\frac{L_g}{k_g}+\frac{L_a}{k_a} +\frac{L_o}{k_g}+\frac{1}{h_2} \\\\R"=\frac{1}{10}+\frac{0.003}{0.78}+\frac{0.012}{0.026} +\frac{0.003}{0.78}+\frac{1}{25} \\\\R"=0.1+0.00385+0.46154+0.00385+0.04\\\\R"=0.60924\ K.m^2/W\)

Area = A = height * width = 1.5 m × 2.4 m = 3.6 m²

The change in temperature = ΔT = 20 °C - (-5 °C) = 25 °C

The rate of heat loss is given as:

\(\dot {Q}=A*\frac{\Delta T}{R"}= 3.6*\frac{25}{0.60924}\\ \\\dot {Q}=147.73\ W\)

The inner surface temperature (Ti) is given as:

\(T_i=T-\frac{\dot {Q}}{A} *\frac{1}{h_1}\\ \\T_i=20-\frac{147.73}{3.6}*\frac{1}{10}=15.9\ ^oC\)

If you took CS1 in Python, you likely used negative index numbers to access list elements or sting characters from the back of the sequence. This feature is not built into Java, but you can write code to simulate it. In case you did not take CS1 in Python, here is an example of negative indexing:
list: [university, college, school, department, program]
positive indexes: 0 1 2 3 4
negative indexes: -5 -4 -3 -2 -1
-1 is the last element, -2 is the second-to-last element, -3 is the third-to-last element, and so on.
Implement the pyGet method to get an element from the input list using a positive or a negative index. Apply the following rules:
if index is a valid positive index, return the list item at that index
if index is a valid negative index, convert to the corresponding non-negative index and then return the list item at that non-negative index
if index is too large, create an ArrayIndexOutOfBoundsException with message index X is too large, replacing X with the actual value of index
if index is too small, create an ArrayIndexOutOfBoundsException with message index X is too small, replacing X with the actual value of index
Suppose that the list has 5 items (as shown in the initial example) but the input index is -6. Then the message string should look like this:
index -6 is too small

}

This code defines the pyGet method that takes an ArrayList and an index as parameters. It checks whether the index is within the valid range for positive and negative indexing and retrieves the corresponding element from the list. If the index is out of bounds, it throws an ArrayIndexOutOfBoundsException with the appropriate error message.

The code then demonstrates the usage of pyGet by providing a sample list and testing various indexes, including one that is expected to throw an exception.

#SPJ11

a tensile specimen with a 12mm initial diameter and 50mm gage length reaches maximum load at 90KN and fractures at 70KN

the minimum diameter at fracture is 10mm

determine the engineering stress at maximum load and the true fracture stress.

Answers

Answer:

i) 796.18 N/mm^2

ii) 1111.11 N/mm^2

Explanation:

Initial diameter ( D ) = 12 mm

Gage Length = 50 mm

maximum load ( P ) = 90 KN

Fractures at =  70 KN

minimum diameter at fracture = 10mm

Calculate the engineering stress at Maximum load and the True fracture stress

i) Engineering stress at maximum load = P/ A

= P / \(\pi \frac{D^2}{4}\)  = 90 * 10^3 / ( 3.14 * 12^2 ) / 4

= 90,000 / 113.04 = 796.18 N/mm^2

ii) True Fracture stress =  P/A

= 90 * 10^3 / ( 3.24 * 10^2) / 4

= 90000 / 81  =  1111.11 N/mm^2

Moment of inertia about x-axis:

I₁= 1/12 (200) (12)³ + (200) (12) (104)²

 = 25.9872×10⁶ mm⁴

I₂= 1/2 (8) (196)³ = 5.0197×10⁶ mm⁴

I₃= I₁ = 25.9872 × 10⁶mm⁴

I = I₁ + I₂ + I₃

 = 56.944×10⁶ mm⁴ = 56.944×10⁻⁶ m⁴

σ = MC/I  with C= 1/2(220) = 110mm = 0.110m

M = Iσ /C with σ= 155× 10⁶ Pa

Mₓ = (((56.944×10⁻⁶) ( 155× 10⁶))/ 0.110) = 80.2×10³N.m

Mₓ = 80.2kN.m

Signal loss is the reduction of a signal that occurs in a medium as a function of the physical length of the channel. This is known as:_________

a. degradation.
b. attenuation.
c. frequency degradation.
d. amplitude degradation.

Answers

Answer:

B) Attenuation

Explanation:

Attenuation can be regarded as the loss of signal strength which could be as a result of both external and internal factors. This loss of signal strength could occur in networking cables as well as other connections. Attenuation is a loss in energy, because as signal travels, its strength decreases as a a result of distance it covers, this loss of energy is due to the signal trying to overcome the resistance at the medium. One of the main the causes of attenuation is When there is Extra noise on available networks, networks such as electrical current as well as radio waves. It should be noted that attenuation is Signal loss which is the reduction of a signal that occurs in a medium as a function of the physical length of the channel.

Singnal attenuation can taken care of by using lower loss materials with high cost, instead of making of PCB routing length reduction. Amplifiers can also be engaged in amplifying attenuated signal to get back the original signal, this will compensate the loss.

Attenuation can be measured in decibels(dB), this gives the measurement of relative strengths of one signal at two different point or measurement of two signals.
