A steel bar is attached to a wood support beam with four 21 mm diameter lag screws, as shown in the figure. The steel bar is 66-mm-wide by 9-mm-thick. The yield strength of the steel is 265 MPa and the ultimate bearing strength is 345 MPa. For the lag screws, the ultimate shear strength is 160 MPa. If a factor of safety of 1.85 with respect to yield strength, 3.5 with respect to bearing strength, and 2.8 with respect to shear strength is required, determine the allowable load P that can be supported by this connection. For the yield strength criterion, consider the constant cross-section part of the steel bar.
