The A-36 steel pipe has a 6061-T6 aluminum core. It issubjected to a tensile force of 200 kN. Determine the averagenormal stress in the aluminum and the steel due to thisloading. The pipe has an outer diameter of 78 mm and aninner diameter of 36mm.
Answers
Force applies normal (perpendicular) to an object's surface in steel (48.79 kPa) and aluminum (0.1625 kPa), exerting a normal stress.
What does "normal stress" mean?
Stress, as its name indicates, is described as When the direction of the deforming force is parallel to the body's cross-sectional area, there is normal stress. If the wire's length or the body's volume changes, the stress level will remain normal.
What are typical strain and stress?
The Greek symbol epsilon designates normal strain, which happens when an item stretches in response to a normal tension (i.e., one that is perpendicular to a surface). Positive values represent tensile strains, whereas negative values represent compressive strains.
Briefing:
The steel pipe will have a section of:
A1 = π/4 * (D^2 - d^2)
A1 = π/4 * (0.78^2 - 0.36^2) = 0.3760 m^2
The aluminum core:
A2 = π/4 * d^2
A2 = π/4 * 0.36^2 = 0.1017 m^2
The parts will have a certain stiffness:
k = E * A/l
We don't know their length, so we can consider this as stiffness per unit of length
k = E * A
For the steel pipe:
E = 210 GPa (for steel)
k1 = 210*10^9 * 0.3760 = 7.89*10^10 N
For the aluminum:
E = 70 GPa
k2 = 70*10^9 * 0.1017 = 0.711*10^10 N
Hooke's law,
Δd = f / k
Since we are using stiffness per unit of length we use stretching per unit of length,
ε = f / k
When the force is distributed between both materials will stretch the same length,
f = f1 + f2
f1 / k1 = f2/ k2
Replacing:
f1 = f - f2
(f - f2) / k1 = f2 / k2
f/k1 - f2/k1 = f2/k2
f/k1 = f2 * (1/k2 + 1/k1)
f2 = (f/k1) / (1/k2 + 1/k1)
f2 = (200000/7.89*10^10) / (1/0.711*10^10 + 1/7.89*10^10) = 16532.96 N = 16.532 KN
f1 = 200 - 16.53 = 183.47 kN
Then we calculate the stresses:
σ1 = f1/A1 = 18347 / 0.3760 = 48795.21 Pa = 48.795 kPa
σ2 = f2/A2 = 16.532 / 0.1017 = 162.556 Pa = 0.16255 kPa

Answers
Answer:
32000 bits/seconds
Explanation:
Given that :
there are 16 signal combinations (states) = 2⁴
bits n = 4
and a baud rate (number of signals/second) = 8000/second
Therefore; the number of bits per seconds can be calculated as follows:
Number of bits per seconds = bits n × number of signal per seconds
Number of bits per seconds = 4 × 8000/second
Number of bits per seconds = 32000 bits/seconds

Oxy-fuel cutting is used for the cutting of mild steel. Only metals whose oxides have a lower melting point than the base metal itself can be cut with this process. Otherwise as soon as the metal oxidises it terminates the oxidation by forming a protective crust.
oncrete left in air as early as possible will reach full strength after several years. b. concrete curing is not necessary for slabs, only walls. c. concrete left in air after 7 days will have approximately 90 percent of its full strength at 28 days. d. concrete cured under water will have its full strength exactly at 90 days. e. concrete hardening continues at subfreezing temperatures, albeit slowly.
Answers
a. True. Concrete gains strength over time through a process called hydration, where the cementitious materials react with water to form a hardened matrix.
While concrete may reach sufficient strength for certain applications within a few days, it typically continues to gain strength for several years until it reaches its full strength potential.
b. False. Concrete curing is necessary for both slabs and walls. Curing involves providing favorable conditions, such as maintaining moisture and temperature, to allow the hydration process to proceed efficiently. Proper curing helps prevent cracking, enhances durability, and promotes the development of desired strength properties in both horizontal (slabs) and vertical (walls) concrete elements.
c. True. Concrete gains strength with time, and typically, it reaches around 90 percent of its full strength at 28 days of curing. This time frame is commonly used as a benchmark for evaluating concrete strength and determining its suitability for various applications.
d. False. The time required for concrete to reach its full strength can vary depending on several factors, including mix design, curing conditions, and environmental factors. While curing concrete underwater can help maintain moisture levels and promote hydration, achieving full strength exactly at 90 days cannot be generalized.
e. True. Concrete hardening can continue at subfreezing temperatures, although at a slower rate compared to higher temperatures. Adequate protection measures are necessary during freezing conditions to prevent the formation of ice crystals, which can cause damage to the concrete structure. Proper curing techniques, such as using insulation or heating methods, can facilitate the hardening process even in cold environments.

Kim deposits her annual bonus into a savings account that pays 8% interest compounded annuallyThe size of her bonus increases by $2,000 each year, and the initial bonus amount is $5,000. Determine how much will be in the account immediately after the fifth deposit
Answers
The amount that would be in Kim's account immediately after the fifth deposit would be $50,998.0
How to find the amount that would be in the accountWe have the amount in Year 0 to be the first deposit. This is given as $5000.
The formula used to calculate this is
P x (1+r) + T
Where P = principal
r = interest rate, hence 1 + 8% = 1.08
T is the increases of 2000
The bonus is said to increase by 2000 every year
2000 + 5000 = $7000
In year 1.
5000 x 1.08 + 7000
= 12,400
In year 2 add 2000 to 7000
(12,400 * 1.08) + 9000
= 22,392
Do the same for year 3
(22,392 * 1.08) + 11,000
= 35,183.36
Do the same for the 4th year
(35,183.36 * 1.08) + 13,000
= $50,998.0288
Therefore we can see that after the deposit is done 5 times the account would have $50,998.02 in it

Answers
Recent scholarship questions the derivation of the architectural orders from wood, proposing instead that the orders developed from a monumental decorative style using molded stone details.
Various scholars argue that architectural orders could not have evolved from wood designs due to the brittle and ephemeral nature of the wood; it cannot bear the weight of any significant structure or long-lasting framework without collapsing, therefore implying that the system had to be changed to develop a new system of permanent construction. Instead of woods, the orders might have originated from some other materials that could carry the weight of the building. The stone was an appropriate material that could stand up to the rigors of the environment and could be carved into the shapes required for structures such as columns.

Determine the Productivity Index (PI) for this well
Answers
The productivity index (PI) for this well is 6.9 STB/day/psi.
The Productivity Index (PI) for this well is approximately 6.9 STB/day/psi.What is Productivity Index (PI)?Productivity index (PI) is a performance metric used to assess the capacity of an oil or gas well to produce hydrocarbons. It is a measure of the well's productivity that relates to the pressure drop across the wellbore's reservoir section and the flow rate of fluids (oil, gas, or water) from the reservoir into the wellbore.When the PI value is high, it means the well is very productive. When the PI is low, it means that the well is not very productive.The formula for the Productivity Index (PI) is as follows:PI = (2πkhd)/(μln(r_e/r_w) + s)Where:k = average permeability, mdh = net reservoir thickness, ftμ = fluid viscosity, cpd = drainage area, acr = wellbore radius, fts = skin factorPI Calculation:Given data,Net pay thickness (h) = 75 ftNet to gross ratio = 0.9Porosity (φ) = 6.5%Average permeability, k = 2 md and 15 md in the vertical and horizontal directions, respectivelyRelative permeability (kro) = 0.82Oil viscosity (μ) = 0.55 cpFormation volume factor (Bo) = 1.22 bbl/STBWellbore radius (rw) = 6 in. or 0.5 ftDrainage area (Ad) = 55 acres = (55 × 43560) ft² = 2395800 ft²Well length (L) = 1500 ftSkin value (s) = 0.8Correction factor for wellbore friction = 1.0The first step is to calculate the effective drainage radius (re) using the formula,re = (0.00708 × (φ^2) × (kh/μ))^(1/2)× (kro/Bo) × ln(r_e/r_w)Let's plug in the values of given parameters,re = (0.00708 × (0.065^2) × ((2+15)/2/μ))^(1/2) × 0.82/1.22 × ln(r_e/r_w)re = (0.04226/μ)^(1/2) × ln(r_e/r_w)We know, k = 2 md and 15 md in vertical and horizontal directions.

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.
A hydroelectric turbine passes 1.7 million gal/min through its blades. If the average velocity of the flow in the circular cross-sectional conduit leading to the turbine is not to exceed 34 ft/s, determine the minimum allowable diameter of the conduit.
Answers
Answer:
11.87 ft
Explanation:
Volumetric flow rate of the turbine Q = 1.7 million gal/min
Q = 1.7 x \(10^{6}\) gal/min
1 gal = 0.00378541 m^3
1 min = 60 sec
1.7 x \(10^{6}\) gal/min = (1.7 x \(10^{6}\) x 0.00378541)/60 = 107.25 m^3
average velocity of flow through turbine = 34 ft/s
1 ft = 0.3048 m
34 ft/s = 34 x 0.3048 = 10.36 m/s
According to continuity equation, Q = AV
where Q = volumetric flow rate
A = Area of conduit
V = velocity of flow through turbine
A = Q/V = 107.25/10.36 = 10.35 m^2
Area of conduit = \(\pi r ^{2}\)
radius r = \(\sqrt{\frac{area}{\pi } }\) = \(\sqrt{\frac{10.35}{3.142} }\) = 1.81 m
diameter = 2 x radius = 2 x 1.81 = 3.62 m
diameter = 3.62 m = 3.62 x 3.28084 = 11.87 ft

These days, many gas, petroland many of the oil engines run on this cycle. It is also known as constant volume cycle, as the heatis received and rejected at a constant volume
This cycle is taken as a standard of comparisonfor internal combustion engines. For the purposeof comparison with other cycles, the air isassumed to be the working substance.•
The ideal Otto cycle consists of two constantvolume and two reversible adiabatic orisentropic processes as shown fig:Otto Cycle•
Processes of Otto Cycle:•
Process 1-2: Isentropic compression•
Process 2-3: Constant-volume heat additiont
Process 3-4: Isentropic expansion• Process 4-1: Constant-volume heat rejection
According to the Otto Cycle, heat engines use gasoline to propel themselves. This cycle also converts chemical energy into thermal energy, which is ultimately converted into motion. The Otto cycle explains the operation of internal combustion engines (which use gasoline), such as those found in cars and lawnmowers.
The Otto Cycle was crucial to the development of the modern world and supplies the energy for the majority of transportation. Specifically, the Otto Cycle is used by the great majority of vehicles on the road today to turn gasoline into motion.

The velocity ratio of a chain drive is 10. The diameter of the input sheave is 38 cm and it is rotating at a speed of 22 rad⁄s. Find the diameter of the output sheave and its angular velocity
Answers
In a chain drive, the velocity ratio is the ratio of the output velocity to the input velocity. It is denoted by the symbol V.R. The formula for velocity ratio is V.R. = output velocity/input velocity.In this problem, the velocity ratio of the chain drive is given as 10.
Therefore, the output velocity is 10 times the input velocity. The diameter of the input sheave is 38 cm and it is rotating at a speed of 22 rad/s. To find the diameter of the output sheave and its angular velocity, we need to use the formula for velocity ratio and the formula for linear velocity.Linear velocity is the velocity of a point on a rotating object.
It is given by the formula v = ωr, where v is the linear velocity, ω is the angular velocity, and r is the radius or distance of the point from the axis of rotation.Velocity ratio = Output velocity/Input velocityV.R. = ω2r2/ω1r1Where ω1 is the angular velocity of the input sheave, r1 is the radius of the input sheave, ω2 is the angular velocity of the output sheave, and r2 is the radius of the output sheave.
