A load of 16 kN is apsplied normal to the gravity axis at a distance of 300 mm from the centre of gravity of welds. Find maximum shear stress in the welds, assuming each weld to be 100 mm long and parallel to the axis of the angle.

Figure 2.1. shows two long plates with same material and equal width w=20 mm that are subjected to a uniaxial tensile load o. One of the plates has a single small central hole with diameter 4mm and another plate has two small holes with a distance of 8mm from each other. The holes are perpendicular to the external tensile load.
