Question

"One end of a steel rod of radius R = 10mm and length L = 90 cm is held in a vise. A force of magnitude F = 70000 N is then applied perpendicularly to the end face (uniformly across the area) at the other end, pulling directly away from the vise. What will be the elongation of the rod (in the unit meters)? Young modulus is 200 × 109 N/m2)"
