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 = 340 mm2 and a length of L1 = 3.6 m.  Rod (2) has an area of A2 = 315 mm2 and a length of L2 = 1.2 m.  Assume dimensions of a = 3.4 m, b = 1.2 m, and c = 1.5 m.  After a load of P = 60 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.

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 = 340 mm2 and a length of L1 = 3.6 m.  Rod (2) has an area of A2 = 315 mm2 and a length of L2 = 1.2 m.  Assume dimensions of a = 3.4 m, b = 1.2 m, and c = 1.5 m.  After a load of P = 60 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.
