Question 1.
What is the impulse response function also known as?
Show hintHide hint
Think about the function that describes systems' responses.
Question 2.
What does a unit impulse input represent?
Show hintHide hint
Remember the mathematical representation of an impulse.
3Question 3.
What does the impulse response function help to analyze?
- Only damped systems
- Responses to arbitrary forces
- Static forces
Show hintHide hint
Consider the broader implications of the impulse response.
4Question 4.
True or False: Green's Function is only applicable to undamped systems.
- True
- False
Show hintHide hint
Remember the definition of linear time-invariant systems.
Question 5.
Given a system with a known impulse response function h(t) = e^{-t} cos(2t), compute the response x(t) to an external force F(t) = sin(t) for 0 ≤ t ≤ 10.

Don't forget to break down the convolution process step by step.
Question 6.
If a structure responds to an impulse at t=0 with a maximum displacement of 0.5m and then gradually decreases, describe how you would assess its performance using impulse response functions.
