3) Special problem: The piece of material, shown below, has undeformed dimensions of: L=3 in., and L,=2 in., and L =1 in. The Young's modulus and Poisson's ratio are give below. Two loads, P, and P, are applied, as shown below. L=3 in. Ly =2 in. L-1 in. E- 10 ×10 psi %3D y= 1/4 P = 300 Ib. P,= 600 lb. Determine the in change length in the a) x-direction, &, b) y-direction, &, and c) z-direction, &. Specify longer, shorter, or zero. (By the way, part a) is a good no-calculator problem!) [Ans.: a) & = 6.0x10-$ (shorter), b) & = 4.75x10 (longer), c) &= 1.25×10- (shorter)] !! 1 P, L-1 in. 4-2 in. P.
