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 1.50 in.² and a yield strength of 37 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 66 ksi. Each pin connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.4 with respect to its yiel strength. The minimum factor of safety required for pins B, C, and D is 3.5 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 = 47 in. and b = 96 in. D (1) b a B

Transcribed Image Text: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 1.50 in.² and a
yield strength of 37 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 66 ksi. Each pin
connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.4 with respect to its yield
strength. The minimum factor of safety required for pins B, C, and D is 3.5 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 = 47 in. and b = 96 in.
