Determine:

a. max allowable Pu if the shearing if 0.5in bolts dia. governs

b. max allowable Pu if the bearing of the tension member governs

c. max allowable Pu if all "actions" are considered

d. number of anchor bolts needed if an A992 steel bolt is used instead of A325. Assume force is equally shared by the bolts, and the anchor bolts are properly bonded on the ceiling

A tenslon member 6inx0.Sin (made of A992 steel) is to be anchored to the celling as shown using for 0.75 dia. A108 steel anchor bolts. The tenslon member is connected to the two
angle bars (A992 steel) thru four 0.5in dia. A325 steel bolts. The allowable tension stress for A992 steel is 50 ksi. Assume allowable bearing stress is 1.5 times the allowable tersile stress
for A992. The allowable shear stress for A325 steel is 675 ksi; and the allowable tension stress for A108 steel is 65 ksi. Determine the (a) max allowable Pu if shearing of O.Sin bolts dia
