A circular rod and a 3/8-in.-thick rectangular bar are both made of a plastic material that has an elastic modulus of E = 2.7 GPa and a Poisson's ratio of v=0.4. The rod and the bar are initially the same length L. After a particular load is applied, the 3.5-in-wide rectangular bar is elongated by some amount AL and its width is reduced by 0.093 in. If the 1.25-in. diameter rod is stretched by the same amount AL, determine its change in diameter. Expansion is positive, while contraction is negative. Circular Rod Rectangular Bar Answer: Ad = i original diameter original width L in. AL
