Question
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 1.25 in.² and a
yield strength of 46 ksi. The pins at B, C, and D each have a diameter of 0.3 in. and an ultimate shear strength of 76 ksi. Each pin
connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.8 with respect to its yield
strength. The minimum factor of safety required for pins B, C, and D is 2.7 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 = 53 in. and b = 108 in.
