A36 steel; E70 electrodes; 5/16 inch fillet welds; P, = 300 kips

A tension member (C15 x 33.9) is welded to a t x 16.5 in. gusset plate. Compute the minimum acceptable thickness for the gusset plate due to yielding on A,. Use the preferred increment for thickness on LRFD pl-133 and choose the actual minimum acceptable thickness that can be used. Each end return of the weld group is 0.25d, where d = depth of C15 x 33.9 section. Find the minimum value of L, that satisfies the design requirement for the welds.
