A simply supported beam with a length of 4m is loaded with a uniform distributed load (w).
The beam has a rectangular hollow section with the following dimensions:
Outer Base = 150 mm Outer Depth = 200 mm
Inner Base = 100 mm Inner Depth = 150 mm
Determine the maximum uniformly distributed load which can be applied over the entire length of the beam if the bending stress is limited to 8 Mpa.
Can you show me the step by step solution
