Question

Rigid bar ABCD is loaded and supported. Steel [E=30,000 ksi] bars (1) and (2) are unstressed before the load P is applied. Bar (1) has a cross-sectional area of 0.625 in.² and bar (2) has a cross-sectional area of 1.25 in.². After load P is applied, the strain in bar (2) is found to be 900 με. If there is a clearance of 0.05 in. in the pin connection at C, determine:

(a) the stresses in bars (1) and (2).
(b) the vertical deflection of point D.
