Problem #7, Please only do 1.52
1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and
has a x-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 con
nected to its support at B by a f-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 may
be applied at D. Note that link AC is not reinforced around the pin holes
1.52 Solve Prob. 1.51, assuming that the structure has been redesigned
-in.-diameter pins at A and C as well as at B and that no other change
has been made.
