An equal angle section 100mm $\times$ 100mm $\times$ 8mm is welded to a gusset plate to serve as a tension member. Calculate the minimum amount of overlapping by the angle section on the gusset plate with a view to limit the induced stress to 100 mega pascal in the angle section when only the side welds are used. The effective area of angle may be taken as the area of the connected leg plus half the area of the unconnected leg. The safe stress in the weld is 90 mega pascal and the shock factor is 1.5.
