A channel shape is used to support the loads on the beam below. The dimensions of the shape of the beam is also given. Consider the entire 12-ft length of the beam and determine the stress at the top and bottom of the beam.

A Universal beam of I shaped cross-section is 203 mm deep, and 133 mm wide and has a steel plate 150 mm by 10 mm thick fastened to each flange. Ix-x for the universal beam is 28.80×10^6 mm^4. a) Determine the total uniformity distributed load which may be carried over a simply supported span of 6 metres if the permissible bending stress is 165 N/mm^2. Neglect the self-weight of the beam. [Ans.: 124.02 KN/m] b) Determine the minimum central length over which the additional plates are required. [Ans.: 4.23m]
