Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 14 × 1214⁢ × 12 -in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by 3838 -in.-diameter pins, while member BCD is connected to its support at B by a 516516 -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 3.05 is desired, determine the largest load P that can be applied at D. Note that link AC is not reinforced around the pin holes. The largest load P that can be applied at D is lb.

(4) The plunger of an oil pump is held against the operating cam by a spring made of No.10 W&M gage steel wire coiled with an outside diameter of ⅞-in. There are five active coils. The open length is 1.1875in. What are the length & stress when a load of 30lb is applied.
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.
