2. The bar shown below has undeformed dimensions: length, L = 10 in. and height, h = 2 in. The Young's modulus is E = 20 Msi and Poisson's ratio is V =1/5. An axial load, P = 30 kips is applied to the rod, as shown below. The maximum allowable changes in length in the x- and y-directions are: 5 =4.0x10-3 in. and 6 =1.0x10 in. Determine the smallest allowable width, w, for the bar. (Hint: must check both conditions.) Ans: w = 3.0 in. W V h P P Z X L
