Question
Rigid bar ABCD is loaded and supported as shown. Steel [E = 29800 ksi] bars (1) and (2) are unstressed before the load P is applied. Bar (1) has a cross-sectional area of 0.86 in.² and bar (2) has a cross-sectional area of 0.47 in.2. After load P is applied, the strain in bar (1) is found to be 780 μe. Assume L₁-52 in., L₂=74 in., a=20 in., b=25 in., and c-33 in. Determine: (a) the stresses in bars (1) and (2). (b) the vertical deflection vp of point D on the rigid bar. (c) the load P.
