A steel bar, with a rectangular cross section, has a butt-welded joint, as shown below, and will be used to carry an axial tensile load of 750 kN. If the normal and shear stresses on the plane of the weld must be limited to 80 MPa and 50 MPa, respectively, determine the minimum thickness t required for the bar.
