Example: 4 A prismatic steel bar having cross sectional area of A=300 mm? is subjected to axial load as shown in figure . Find the net increase & in the length of the bar. Assume E = 2 x 10 5 MPa.( Ans ô = -0.17mm) %3D 20 kN 15 kN 15 kN В A 2 m 1m, m 1m 15 A 15 0 – B 20 C 20 Solution: 8 = 20000*1000/(300*2x10 5)-15000*2000/(300*2 x10 5) = 0.33 - 0.5 = -0.17 mm (i.e.contraction)
