1-55: In the structure shown, an 8 mm diameter pin is used at A, and 12-mm- diameter pins are used at B and D. Knowing that the ultimate shearing stress is 100 MPa at all connections and that the ultimate normal stress is 250 MPa in each of the two links joining B and D, determine the allowable load P if an overall factor of safety of 3.0 is desired.

1-55: In the structure shown, an 8 mm diameter pin is used at A, and 12-mm-
diameter pins are used at B and D. Knowing that the ultimate shearing stress is
100 MPa at all connections and that the ultimate normal stress is 250 MPa in
each of the two links joining B and D, determine the allowable load P if an
overall factor of safety of 3.0 is desired.
