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.
