Question

At an axial load of 22 kN, a 45-mm-wide x lS-mm-thick polyimide polymer bar
elongates 3.0 mm while the bar width contracts 0.25 mm. The bai is iOO mm'long. At the
22-ld{ load, the stress in the polymer bar is less than its proportional limit. Deterriine: (a)
the modulus of elasticity (b) Poisson's ratio (c) the change in the bar thickness
