Determine the nominal block shear strength of a L8 x 8 x 9/16 consisting of A36 steel that is attached through one leg to a gusset plate with two 5/8-inch-diameter bolts. Assume a = 3 in., b = 1.5 in., and c = 6.25 in.

Determine the nominal strength for the following PL 7/16 x 8 plate of A36 steel with two holes for 3/4-inch-diameter bolts. Assume a = 2.5 in., b = 3 in., and c = 2 in.

Determine the net area for an MC12 x 35 with five lines of 7/8-inch-diameter bolts. Each flange will contain one line of bolts, and the web will contain three lines of bolts. The bolts are not staggered.
