Problem 2:
Design the most economical double angle (2L4) back-to-back tension member fabricated from
A36 steel material to carry a service dead load of 40 kips and a service live load of 55 kips. Assume
that the member is 30-ft long and connected to a 3/4-in thick gusset plate with eight 1/2-in bolts
distributed on two lines as shown in the figure below. Ignore block shear in this problem and
assume that the gusset does not control.
