gid bar ABC is supported by member (1) at B and by a pin connection at C. Member (1) has a cross sectional area of 1.35 in.² and a eld strength of 42 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 76 ksi. Each pin nnection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.9 with respect to its yield rength. The minimum factor of safety required for pins B, C, and D is 2.7 with respect to the pin ultimate shear strength. Determine e allowable load P that may be applied to the rigid bar at A. Use overall dimensions of a = 50 in. and b = 102 in.

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 1.35 in.² and a
yield strength of 42 ksi. The pins at B, C, and D each have a diameter of 0.7 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 1.9 with respect to its yield
strength. The minimum factor of safety required for pins B, C, and Dis 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 = 50 in. and b = 102 in.
