Question

At an axial load of 22 kN, a 15-mm-thick × 40-mm-wide polyimide polymer bar elongates 4.1 mm while the bar width contracts 0.15 mm. The bar is 270 mm long. At the 22 kN load, the stress in the polymer bar is less than its proportional limit. Determine Poisson's ratio.

Step 1

The bar has a thickness of 15 mm and a width of 40 mm. \[ A = \text{thickness} \times \text{width} = 15 \, \text{mm} \times 40 \, \text{mm} = 600 \, \text{mm}^2 \] Show more…
