Q2. The figure shows a horizontal steel bar of thickness, 3 mm, loaded in steady tension and welded to a vertical support. Find the load F that will cause an allowable shear stress, Tallow = 140 MPa, in the throats of the welds. For the weldments, the electrodes are specified as E6010. For the electrode metal indicated, what is the allowable load on the weldment?

A flat bar (thickness b = 10 mm) with a shoulder fillet is loaded by a cyclic force F-10-2013 shown below. The bar is made of alloy steel (S. = 900 MPa, S, - 700 MPa) and has dimensions of 35 mm, H = 50 mm, r = 4 mm and I = 80 mm. The actual fatigue strength of the component is estimated as S = 360 MPa for commercially polished surface conditions. The bar should be safe against...
