Question

In the figure, davit ABD is supported at A by a single shear pin connection and at B by a tie rod (1). The pin at A has a diameter of 1.29 in. and the pins at B and C are each 0.74-in.-diameter pins. Tie rod (1) has an area of 1.68 in.2. The ultimate shear strength in each pin is 96 ksi, and the yield strength of the tie rod is 52 ksi. A concentrated load of 25 kips is applied as shown to the davit structure at D. Determine:
(a) the normal stress in rod (1).
(b) the shearing stress in the pins at A and B.
(c) the factor of safety with respect to the yield strength for tie rod (1).
(d) the factor of safety with respect to the ultimate strength for the pins at A and B.
