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 ulti- mate 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 Band D. Knowing that the ulti-
mate 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.
