Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A beam is subjected to two different loads at opposing ends. Determine the deflection at the midpoint using the Principle of Virtual Work. Assume all materials are linearly elastic.

💡 Hint: Break down the forces and apply them step-by-step.

Challenge 2 Hard

Analyze a truss structure using the Principle of Virtual Work to evaluate the impact of an external load applied at a joint and derive the reactions at the supports.

💡 Hint: Outline the forces and remember to account for all angles.
