Question

Rigid bar ABCD is loaded and supported. Bars (1) and (2) are unstressed before the load P is applied. Bar (1) is made of bronze [E= 100 GPa] and has a cross-sectional area of 400 mm². Bar (2) is made of aluminum [E= 70 GPa] and has a cross-sectional area of 600 mm². After the load P is applied, the force in bar (1) is found to be 60 kN (in compression). Determine:

(a) the stresses in bars (1) and (2).
(b) the vertical deflection of point A.
(c) the load P.
