Challenge Problems
Push your limits with challenges.
Question 1
A simply supported beam with a point load at its center stores how much energy when it bends? Calculate using appropriate bending moment and curvature relations.
💡 Hint: Use the load to determine the maximum moment and apply it to the energy equation.
Question 2
Given a beam with varying cross-section, derive the general expression for bending energy considering the moment of inertia's variation.
💡 Hint: Reflect on how integration over varying cross-sections influences overall energy.
