Challenge Problems
Push your limits with advanced challenges
Consider a rectangular building that is asymmetrical along one axis. Calculate the expected torsional response if the center of mass is 2 meters from the center of stiffness. Assume the torsional spring constant to be known.
💡 Hint: Understand how to relate torque to angular displacement.
Design a hypothetical building with noted dimensions and mass distribution such that it minimizes torsional effects. Present calculations and justify design choices.
💡 Hint: Think about structural layout and materials used.
