A 3/4 in. x 8 in. plate must resist a service dead load of 32 kips and a service live load of 52 kips in tension. The plate is connected to a gusset with six 1-1/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 42: Fy = 42 ksi, Fu = 60 ksi. Assume that Ae = An. Using ASD, does the plate have enough strength?
