11)lf length of a fillet weld is I and leg length is h, then area of throat can be given by:

11.16 Two 20-mm steel plates are butt-welded together. Both the plate and the welding electrode materials correspond to strength properties of Su = 500 MPa and S, = 400 MPa. The imposed loading fluctuates rapidly between -20 and +60 kN. Estimate the length of weld required in order to provide a safety factor of 2.5: (a) If the weld reinforcement is not removed. (b) If the excess weld material is carefully ground off to provide smooth, continu- ous surfaces.

5. A steel cylindrical air receiver with 5 feet diameter and pressure load of 180 psi, design stress of 9500 psi maximum. The pressure vessel is to be provided with a 1.5 in diameter drain valve installed at the bottom of the vessel and a safety pressure relief valve is installed either at the topmost or at the side with a pop-out rating of 200 psi. Assume a 100% weld joint efficiency. The lap welding tensile strength is 65,000 psi. Determine the bursting pressure of this air receiver. psi

The beam is a wide flange beam section with the following geometry: H = 200 mm, B = 200 mm, t1 = 15 mm and t2 = 20 mm. The fillet weld is along the inner line of the wide flange section (denoted as shaded area) with a thickness of 10 mm. The strength of the fillet weld is 160 Mpa. An eccentric axial force is applied at the beam section. N = 150 kN and eccentricity e = 60 mm. Check the strength of the weld design.
