The steel bar has a 20 x 10 mm rectangular cross section and is welded along section a-a. The weld material has a tensile yield
strength of 325 MPa and a shear yield strength of 200 MPa, and the bar material has a tensile yield strength of 350 MPa. An overall factor of safety of at least 2.0 is required. Find the largest load P that can be applied, to satisfy all criteria.
