Challenge Problems
Push your limits with advanced challenges
Design a structural model with three floors where the CM and CS do not align. Explain how you would account for the torsional effects in your analysis.
💡 Hint: Think of how uneven distribution affects stability.
Given a dynamically loaded beam, calculate the expected torsional motion if the CM and CS are 2m apart. Discuss implications for design adjustments.
💡 Hint: Consider the weight distribution and its effect on motion.
