Challenge Problems

Push your limits with challenges.

Question 1

A bridge consists of a single span subjected to a real load of 10 kN at midspan. Use the Virtual Work method to determine the deflection at the central support if a virtual point load of 1 kN is applied also at the midspan.

💡 Hint: Free body diagram and equilibrium equations will aid in simplifying calculations.

Question 2

Design a truss member with real loads of 15 kN and 5 kN applied at two different points. Use the Virtual Work method considering a unit virtual load to analyze and determine the resultant deformation.

💡 Hint: Begin by outlining the connections and points of load application to track how the structure reacts.
