Problem 1.54 Solve Prob. 1.53, assuming that the structure has been redesigned to use 12-mm-diameter pins at B and D and no other change has been made. Problem 1.53 In the steel structure shown, a 6-mm-diameter pin is used at C and 10-mm-diameter pins are used at B and D. The ultimate shearing stress is 150 MPa at all connections, and the ultimate normal stress is 400 MPa in link BD. Knowing that a factor of safety of 3.0 is desired, determine the largest load P that can be applied at A. Note that link BD is not reinforced around the pin holes.
