Determine the allowable load magnitude w that can be applied to the system shown for the following considerations: The diameter of rod CB is 1-inch and the material has a tensile strength ofail=60ksi. The pins at A, B, and C have diameters of 0.5in and shear strengths of Tfail=30ksi. A factor of safety of 3 is required against material failure in the pins and a factor of safety of 1.5 is required against tensile failure of the rod BC. 4 ft W 1 ft 3 ft
