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.
