Rigid bar ABC is supported by member (1) at B and by a pin connection at C. Member (1) has a cross sectional area of 1.15 in.2 and a yield strength of 41 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 72 ksi. Each pin connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.9 with respect to its yield strength. The minimum factor of safety required for pins B, C, and D is 2.6 with respect to the pin ultimate shear strength. Determine the allowable load P that may be applied to the rigid bar at A. Use overall dimensions of a = 51 in. and b = 104 in.
