The assembly is used to support the distributed loaning of w = 10 kN/m. For design purposes, determine the diameter of the rod BC and the pins at B and C. In the design process, a safety factor of 3 against yielding must be considered for the rod and the safety factor for the pins must be 2. Structural steel A36 with a yield strength of 250 MPa in tension and 125 MPa in shear is selected as the material for all the assembly components. 1.2 m 0.9 m B 0.31 W
