Challenge Problems
Push your limits with challenges.
Question 1
A structural beam supports a load of 10 kN. Calculate the strain energy stored in the beam if its length is 3 m, area is 40 cm², and E is 200 GPa.
💡 Hint: Use U = (P^2 L) / (2AE) directly in your calculations.
Question 2
Explain how you would apply the Virtual Work method to assess bending in a simply supported beam with a central load.
💡 Hint: Ensure that you maintain equilibrium for both real and virtual loads.
