A tensile force of 120 kN is applied on a 0.02-m diameter and
2-m long rod. After applying the load, the diameter of the rod
decreases to 0.01998 m and the length increases to 2.01 m. The
engineering stress on that rod is most nearly:

A steel cable with a yield strength of 35 ksi is used to support a load of 10000 lb. Select the diameter of the cable using a factor of safety of 2.5. A standard steel specimen having a diameter of 0.502 in, and a gauge length of 2.00 in is used in a tension test. At 6000 lb the deformation is recorded as 0.00212 in. The load at the yield point is 7130 lb and the ultimate load is 11520...
