Challenge Problems

Push your limits with challenges.

Question 1

A structure is designed with a natural frequency of 2 Hz. If an earthquake produces waves at 2 Hz, discuss the risks involved.

💡 Hint: Consider how matching frequencies might compound the effects of dynamic loads.

Question 2

Consider a building designed with a specific distribution of mass across its floors. Discuss how uneven mass distribution could affect its natural frequency.

💡 Hint: Think about how a seesaw might tilt differently depending on weight placements.
