8 in. B 6 in. 1.5 C 4 in.- D P PROBLEM 1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and has a ½ × ½-in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by-in.-diameter pins, while member BCD is connected to its support at B by a -in.-diameter pin. All of the pins are made of a steel with a 25-ksi ultimate shearing stress and are in single shear. Knowing that a factor of safety of 3.25 is desired, determine the largest load P that can be applied at D. Note that link AC is not reinforced around the pin holes.

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 45 ksi. The pins at B, C, and D each have a diameter of 0.7 in. and an ultimate shear strength of 78 ksi. Each pin connection is a double-shear connection. Specifications call for a minimum factor of safety in member (1) of 1.5 with respect to its yield strength. The minimum factor of safety required for pins B, C, and D is 2.9 with respect to the pin ultimate shear strength. Determine the allowable load P that may be applied to the rigid bar at A.
