An American Standard Channel shape must resist a factored tensile load. The length is 15 ft, and there will be two lines of 7/8-in. diameter bolts in the web, as shown in the figure below. Estimate the shear lag factor U to be 0.85. (In a practical design, once the member and bolt layout are selected, the value of U could be computed and the member design could be revised if necessary.) Use A36 steel. For the steel Fy = 36 ksi and F₁ = 58 ksi. Try the tension members given in the table below. Tension member A, (in.²) tw (in.) ry (in.)
