A high-density polyethylene [E = 128 ksi; a = 88 x 10-6/°F] bar is positioned between two rigid supports, as shown. The bar is square with cross-sectional dimensions of 2.50 in. by 2.50 in. and length L = 48 in. At room temperature, a gap of A = 0.35 in. exists between the block and the rigid support at B. After a temperature increase of 120°F, determine magnitude of the normal stress in the bar. Answer in psi rounded-off to 2 decimal places. L
