The two vertical steel rods [e = 200gpa] that support rigid bar abcd are initially free of stress. rod (1) has an area of a1 = 450mm2 and a length of l1 = 2.2m. rod (2) has an area of a2 = 325mm2 and a length of l2 = 1.6m. the dimensions are: a = 3.0m, b = 1.0m, and c = 1.25m. after a load of p = 80kn is applied to the rigid bar at d, determine: (a) the normal stresses in rods (1) and (2). (b) the deflection of the rigid bar at d.
