A36 steel; E70 electrodes; 3/8-in. fillet welds; L, = 5.25; P, = 270 kips

A pair of L6 x 4 x 7/16 with long legs welded to a w x 3/4 in. gusset plate serves as a tension member. Compute the minimum acceptable value of w for the gusset plate due to yielding on A Assume that the preferred increment for width is 1 /8 in. and choose the actual minimum acceptable w that can be used. Compute the design strength for:

1. Fracture of the fillet welds

2. The gusset plate (yielding on A,; block shear rupture)
