Question

All members shown are initially at a uniform temperature. The two identical horizontal bars (E and FC) each have a an initial length L and are then subject to temperature increases Delta T1 and Delta T2. respectively. Assume that member ABCD is rigid. The horizontal bars each have an area of 1.0 square inches. Calculate the displacement at point D in inches assuming the following parameters: E = 30.698 ksi a steel = 0.0000065 / deg F L = 12 inches a = 5.76 inches Delta T1 = 21 deg F Delta T2 = 25 deg F
