A copper alloy cylinder that is 1.3 feet long with a diameter of 45.27 inch is subjected to a tensile stress of 1,140 psi along its length. Assuming this applied stress is purely elastic, calculate the diameter, in inches, of the cylinder under this load. For this alloy, the elastic modulus is 904,672 psi and the Poisson's ratio is 0.33.

Answer:

diameter = 45.251 inches

Explanation:

initial length = 1.3

initial diameter = 45.27

tensile stress = σ = 1140

modulus E = 904672

v = 0.33

we calculate longitudinal strain = σ/E

= 1140/904672

= 0.0012601252

general relation for

v = -Ed/El

[tex]0.33=\frac{-Ed}{0.0012601252}[/tex]

we cross multiply

-Ed = 0.33 x 0.0012601252

= -0.00041584132in

[tex]\frac{df - 45.27}{45.27} =\frac{-0.00041584132}{1}[/tex]

when we cross multiply,

df - 45.27 = -0.00041584132*45.27

df - 45.27 = -0.018825136

df = -0.018825136 + 45.27

df = 45.251 inches

A rigid insulated tank is divided into 2 equal compartments by a thin rigid partition. One of the compartments contains air, assumed to be an ideal gas at 800 kPa and 300 K. The other compartment is under a vacuum. The partition is suddenly broken and the air rushes into the evacuated compartment. The tank pressure and temperature eventually equilibrate.

a. Define the system you will use and draw a labeled schematic.
b. Write the energy balance for the system, making simplifications as appropriate.
c. What is the final temperature of the gas, K?
d. What is the final pressure, kPa?

A steam power plant is represented as a heat engine operating between two thermal reservoirs at 800 K and 300 K. The temperature of the steam in the boiler is 550 K and the temperature of the saturated water in the condenser is 330 K. The rates of heat transfer in the boiler and condenser are 4 MW and 2 MW, respectively. Please answer the following.

Required:
a. Represent the devices present in the heat engine and include their name along with the data given in the problem.
b. If this steam power plant were to operate as a reversible heat engine, with the boiler and condenser temperatures, what would be its thermal efficiency?
c. Use your result from part (b) to determine if the actual steam power plant can achieve such thermal efficiency. Justify your answer.

The tensile strength of brittle materials may be determined using a variation of Equation 8.1. Compute the critical crack tip radius for an Al2O3 specimen that experiences tensile fracture at an applied stress of 275 MPa (40,000 psi). Assume a critical surface crack length of 2 × 10−3 mm and a theoretical fracture strength of E/10, where E is the modulus of elasticity.
