3. A short compression is 2 inch by 2 inch in cross section and 8 inches long to a 40,000 pounds axial compression load. the length of the it is shorter to 7.85 inches. what is the strain in theobject?

4. an alloy bar stretches for 0.500 inches when it is to an axial tensile of a load of 100k pounds. the bar is 16 feet long and it has a cross sectional area of 2.25 in^2. What are the modulus of elasticity (E). then use a proportional limit of 125 ksi.

I have an hour to finish these.

could you help me please

thank you for your help :)
