Assignment:
A box beam made from an extruded aluminium ally having 5 414 mm wall thickness is loaded by an inclined force P=100 N, as shown in the figure. Determine the maximum stress on section a-b. For the box beam, use the centreline dimension for finding I. (Note that the stress is far away from the support where large local stress concentrations are unlikely.)
Provide complete and step by step solution for the question and show calculations and use formulas.
