If the ultimate tensile strength for an aluminum alloy is 18,000 lbs/in2, and the yield strength is 8,000 lbs/in2 what tensile load can be supported by a rod with a diameter of 0.4 inches?

For the rod in the problem above, at what load does the rod begin to deform plastically?

For problems 6, 7, and 8, why is the length of the sample not included in the information given? Explain in terms of the definition of stress.

The Young’s Modulus (elastic modulus) for tin is 6,000,000 lbs/in2. How much total deflection would you predict if a 10 inch-long sample, with a square cross-section 0.25 inches on a side, is subjected to a load of 3000 pounds?
