Problem 1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 14× 12-in. uniform rectangular cross section. It is con¬nected to a support at A and to member BCD at C by 38-in.-diameter pins, while member BCD is connected to its support at B by a 5 16-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.
