Rigid bar ABCD is supported by a smoth pin at D and by vertical aluminum alloy [E=10,000 ksi] bars attached at joints A and C. Bar (1) was fabricated to its intended length L1=40 in. Bar (2) was intended to have a length of 60 in.; however, its actual length after fabrication was found to be L2=59.88 in. To connect it to the pin at C on the rigid bar, bar (2) will need to be manually stretched by Δ=0.12 in. After bar (2) has been stretched and connected to the pin at C, a load P=20 kips is applied to the rigid bar at B. Use the following additional properties and dimensions: A1=A2=0.75 in2, a = 36 in, b =54 in, and c = 48 in. Determin: a) The normal stresses in bars (1) and (2). b) The deflection at A of the rigid bar.
