The bell crank shown is supported by a single shear pin connection at B and a roller support at C. An external load of P = 2,250 lb at an angle of θ = 53° acts on the bell crank at A. The pin at B has a diameter of d = 1.125 in., and the ultimate shear strength of the pin material is σU = 58,000 psi. Use dimensions of a = 12.0 in. and b = 6.0 in.What is the factor of safety of pin B with respect to its ultimate shear strength?

Rigid bar ABC is supported by pin-connected axial member (1) and by a pin connection at C as shown. A 6,300-lb concentrated load is applied to the rigid bar at A. Member (1) is a 3.25-in. wide by 1.50-in. thick rectangular bar made of steel with a yield strength of σY = 33.3 ksi. The pin at C has an ultimate shear strength of τult = 60 ksi. Determine the factor of safety in member (1) with respect to its yield strength.
