The rigid bar in (Figure 1) is pinned at A and supported by two aluminum rods, each having a diameter of 1.3 in., a modulus of elasticity Eal = 10(10") ksi, and yield stress of (Oy)al = 45 ksi. Part A If the bar is initially vertical, determine the displacement of the end B when the force of 20 kip is applied. Express your answer to three significant figures and include appropriate units.
