Question
![The two vertical steel [E = 200 GPa] rods that support rigid bar ABCD are initially free of stress. Rod (1) has an area of A1 = 410 mm2
and a length of L1 = 3.2 m. Rod (2) has an area of A2 = 355 mm2 and a length of L2 = 1.3 m. Assume dimensions of a = 3.4 m, b = 1.2 m,
and c = 1.5 m. After a load of P = 50 kN is applied to the rigid bar at D, determine:
(a) the normal stresses in rods (1) and (2)
(b) the magnitude of the downward deflection of the rigid bar at D.
