The 80 mm wide plate in the figure is lap-welded to a base plate by one transverse fillet weld across its full width and two equal parallel fillet welds, all of leg size 10 mm. The joint carries P = 160 kN, and the allowable shear stress on the throat of every weld is 75 MPa. Taking throat = 0.707 × leg size and neglecting the allowance for weld ends, determine (a) the load carried by the transverse weld (answer in kN) and (b) the required length L of each parallel weld (answer in mm).
