An overhead crane runs on rails attached to structural columns by means of 25 mm thick mild steel brackets. The brackets are riveted to the column as shown using five 14 mm diameter rivets. The rivets have a shear strength of 100 MPa. Determine if the bracket can safety carry a downwards vertical load of P=20 kN. 1. If the bracket can safely carry the load, determine the factor of safety against eventual failure. 2. If you determine that the...

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 159 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. (Round the final answer to three...
