The pin-connected structure shown in the figure consists of two cold-rolled steel (E = 30,000 ksi) bars (1) and a bronze (E = 15,000 ksi) bar (2) that are connected at pin D. All three bars have cross-sectional areas of 0.375 in². A load of P = 11 kips is applied to the structure at pin D. Using a = 3 ft and b 5 ft, calculate the downward displacement of pin D. = A (1) a B D (2) P a (1) b
