What is the formula for relative displacement?
💡 Hint: Think about how we define the movement of a mass relative to the ground.
If a mass displaces 0.8m during an earthquake with a ground displacement of 0.4m, what is the relative displacement?
💡 Hint: Use the formula for relative displacement.

A building oscillates with a natural period of 1.5 seconds during an earthquake. If the mass displaces 0.75m and the ground moves 0.5m during shaking, find the relative displacement and evaluate the significance of the results.
💡 Hint: Use the subtraction mentioned for ur.
Discuss how varying levels of damping in structures affect their response to earthquake motions. Provide examples of structures with high and low damping characteristics.
💡 Hint: Consider examples of damping systems in real structures.
