One end of a steel rod of radius R = 9.5 mm and length L = 81 cm is held in a bench vise. A force of magnitude F = 62 kN is then applied perpendicularly to the end face(uniformly across the area) at the other end, pulling directly away from the bench vise. (Given: Young’s Modulus for stainless steel is 2.0 ×1011N/m2) Calculate the following; (i) Stress on the rod. (ii) Elongation, ΔL in the rod. (iii) Strain of the rod.
