7. A tension member is subjected to the following unfactored loads: DL = 220 kips and

LL = 185 kips. Select the lightest WT7X__ tension member that can carry the load given

the below bolt pattern. Steel is A36 grade. The bolt diameter is 7/8-inch. Assume that

block shear does not control, so you only need to check yielding of the gross area and

rupture on the net area. (HINT: Design will go faster if you find the minimum required

gross area of steel, Ag). (25 points)
