Chapter 12, Problem 42AP

Review. A wire of length L, Young’s modulus Y, and cross-sectional area A is stretched elastically by an amount ∆L. By Hooke’s law, the restoring force is −kL. (a) Show that k = YA/L. (b) Show that the work done in stretching the wire by an amount ∆L is W = 1 2 Y A ( Δ L ) 2 / L .

Ex 71: Calculate the work done in stretching a wire of diameter 1.2 mm and length 4 m by 0.2 m. Young's modulus of the wire = 2 x 1011 N/m2.
The steel system consists of rod CD, rod AB and a rigid bar AC. The diameter of rods CD and AB are 16 mm and 18 mm, 2.0 m T respectively. If a force of 30 kN is applied to point E, determine: a) the normal stress in rod AB and DC, b) the horizontal displacement of point E. Est = 200 GPa. 0.6 m E 0.3 m 30 kN B 4.0 m A
