Part 1
A cantilever flexural member is fabricated by bolting two
identical cold-rolled steel channels back-to-back, as shown. The
cantilever beam has a span of L = 1300 mm and supports a
concentrated load of P = 500 N. The cross-sectional
dimensions of the built-up shape are shown, where d = 40
mm, w = 65 mm, and t = 3 mm. The effect of the
rounded corners can be neglected in determining the section
properties for the built-up shape....
