Each of the steel links AB and CD is connected to a support and to member BCE by 25-mm-diameter steel pins acting in single shear. Knowing that the ultimate shearing stress is 210 MPa for the steel used in the pins and that the ultimate normal stress is 490 MPa for the steel used in the links, determine the allowable load P if an overall factor of safety of 3.0 is desired. (Note that the links are not reinforced around the pin holes.) 50 mm 12 mm B A 300 mm D C 450 mm E P Each of the steel links AB and CD is connected to a support and to member BCE by 25-mm-diameter steel pins acting in single shear.
