A pin-connected structure is supported and loaded as shown. Member ABCD is rigid and is horizontal before the load P is applied. Bars (1) and (2) are both made from steel [E = 30,000 ksi] and both have a cross-sectional area of 1.5 in.2. Assume lengths of a = 44 in., b = 68 in., c = 28 in., L₁= 50 in., and L₂= 100 in. The normal stress in bars (1) and (2) must be limited to 40 ksi. Determine the maximum load P that may be applied to the rigid bar. Answer in kips rounded-off to 2 decimal places. L₁ Rigid bar b L₂ (2) D
