Question No. 03 (CLO-3). A rigid bar with negligible mass is pinned at O and attached to two vertical rods, figure 1. Assume the rods are initially stress-free. a) Solve to determine the maximum load P that can be applied without exceeding stresses of 120 MPa in the steel rod, 70 MPa in the aluminum rod and the vertical movement of end C is limited to 5 mm. b) Solve to determine the shearing stress in the pin at O. The pin diameter is 20mm. A C 2m 1m 3m Aluminum A=500mm² A=900mm² E=70GPA L=2.0m Steel Detail of E=200GPA L=1.25m pin at O Figure 1: Question No. 3
