Challenge Problems
Push your limits with advanced challenges
Given a cantilever beam with a rectangular cross-section subject to a central point load, calculate the maximum shear stress in the beam. The beam length is 6 m, width is 0.2 m, height is 0.3 m, and total shear force is 10kN.
💡 Hint: Look at the geometry for Q and remember shear force is along the length!
Analyze how shear stress would differ in a composite beam featuring both rectangular and circular cross-sections. Provide the explanation regarding shear force distributions.
💡 Hint: Map out the individual cross-section behaviors before mixing them.
