Challenge Problems
Push your limits with advanced challenges
Suppose you have a beam supported at both ends with a central load and a moment applied at one end. Derive the equations governing the deformation at the midpoint.
💡 Hint: Start by drawing a free body diagram and applying equilibrium equations.
Analyze a scenario where both force and moment are applied on a cantilever beam. How would the maximum stress be calculated, considering contributions from both load types?
💡 Hint: Recall the bending stress equation and how to apply it in different load scenarios.
