Figure 2 [25] QUESTION 3 A pinned-pinned round bar is to be 4m long. It is subjected to a purely axial load. Determine the diameter of the bar and determine the maximum load that it can carry if the bar is made of steel with yield strength of 280 MPa and an elastic modulus of 207 GPa. The safety factor on yield should not exceed 1.5. The moment of inertia for a...

QUESTIONS A truss frame consists of members AB, BC and AC which are made of 25 mm diameter rods. 1. All the joints are pinned. The joint A is pinned to a wall and the joint B is set into a roller which is free to move vertically. The frame supports a point load, P, which is applied at C, as shown in Figure Q1. If the modulus of elasticity of all structures is 210 GPa, yield stress is 200...
