At an axial load of 22 kN, a 15-mm-thick x 50-mm-wide polyimide polymer bar elongates 3.5 mm while the bar width contracts 0.15 mm. The bar is 245-mm long. At the 22-kN load, the stress in the polymer bar is less than its proportional limit. Determine Poisson's ratio. O 0.210 0.195 115 O 0.289 O 0.148 O 0.251
