Question
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 1.25 in.2. If the normal stress in bar (1) must be limited to 19 ksi, determine the maximum load P that may be applied to the rigid bar.
