3 cards from this section. Quick, good the night before a test.
Define inertia in your own words. What does it reflect in a physical context?
Think about how an object behaves when at rest versus when it is in motion.
What is damping in the context of structural engineering?
Consider why a structure needs to not vibrate indefinitely.
What does inertia describe in physics?
Consider how objects react when at rest or in motion.
Damping is necessary in structures primarily because:
Think about what would happen if vibrations never ceased.
A structure experiences ground motion with a mass of 2000 kg, resulting in an acceleration of 3 m/s². Calculate the inertia force.
Remember the inertia force formula.
Given a damping ratio of 0.5, how would this influence the behavior of a structural system during an earthquake? Discuss its significance in terms of safety.
Think about how different damping ratios change the system's response.
