A pin-connected structure is supported and loaded as shown. Member ABCD is rigid and is horizontal before the load Pis applied. Bars (1) and (2) are both made from steel [E - 29000 ksi] and both have a cross-sectional area of 1.15 in.?. Assume L1-73 in., L2-118 in., a=54 in., b=100 in., and c=48 in. If the normal stress in each steel bar must be limited to 15.3 ksi, determine the maximum load P that may be applied to the rigid bar.
