preferred mach in heavy duty structural designs Wood bone concrete and glass have rather small Young s moduli Example 9 1 A structural steel rod has a radius of 10 mm and a length of 1 0 m A 100 kN force stretches it along its length Calculate a stress b elongation and c strain on the rod Young s modulus of structural steel is 2 0 x 10 N m2 Answer We assume that the rod is held by a clamp at one end and the force F is applied at the other end parallel to the length of the rod Then the stress on the rod is given by Stress F AL A The elongation F Tr 100 10 N 3 14 X x 10 m 3 18 x 108 N m 2 F A L Y 2 3 18 x 10 N m2 1m 11 2 10 Nm 1 59 x 10 m 1 1 59 mm The strain is given by Strain AL L 2 1 59 x 10 3 m 1m 50 x 10 3
