Q-4 The polymer bar shown in Figure Q-4 has a width b = 50 mm, a depth d= 100 mm, and a height h= 270 mm. At a compressive load P= 135 kN, the bar height contracts by Ah=-2.50 mm and the bar depth elongates by Ad = 0.38 mm. At this load, the stress in the polymer bar is less than its proportional limit. Determine (a) the modulus of elasticity (E). (b) Poisson's ratio (v). (c) the change in the bar width b (Ab).
