For the following problem, unless noted otherwise refer to Appendices F and G for necessary mechanical properties of materials.
A tension member in a roof truss is composed of two ASTM A36 structural steel angles that together have a net cross-sectional area of 8.62 in2.
(a) Compute the allowable total load if the allowable tensile stress is 22,000 psi.
(b) If the total tensile load in the member is 150,000 lb, compute the actual tensile stress.
