Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the center of mass?
💡 Hint: Think about where the 'balance' point of an object would be.
Question 2
Easy
How many degrees of freedom are needed per floor to account for torsional effects in a building?

Question 1
What result occurs when the center of mass and center of stiffness do not align?
- No effect
- Lateral movement only
- Torsional motion
💡 Hint: Think about how things might rotate if not balanced.
Question 2
True or False: You only need one degree of freedom to account for torsional effects.
- True
- False
💡 Hint: Consider the different ways a building reacts to forces.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
