A tension member constructed of an L 4 x 4 x 1/2 inch angle section (see Table E-4(a) in
Appendix E) is subjected to a tensile load P = 12.5 kips that acts through the point where the midlines of the legs intersect [see figure part (a)].
(a) Determine the maximum tensile stress σt in the angle section.
(b) Re-compute the maximum tensile stress if two angels are used and P is applied as shown in the figure part (b).
