Here is Canvas object wihch demonstrate the problem.

A simply supported beam spans 2,000 mm. A 36-kN concentrated load is applied at midspan.

Determine the stress in each 16-mm bolt.

The beam consists of two C310 × 37 steel channel shapes bolted back-to-back. Pairs of 16-mm-diameter bolts are spaced at 200-mm intervals along the beam span.

Shear flow in back-to-back channels
