A steel bar is attached to a wood support beam with four 20


A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa. The ultimate shear strength of the lag screws is 165 MPa. Factors of safety of 1.70 with respect to yield strength and 3.1 with respect to bearing strength are required for the bar. A factor of safety of 3.0 with respect to the ultimate shear strength is required for the lag screws. Determine the allowable load P that can be supported by this connection. (Note: Consider only the gross cross-sectional area of the bar not the net area.)
