3 cards from this section. Quick, good the night before a test.
Define impulse in the context of forces.
Consider situations where forces are rapidly applied.
What is the Dirac delta function?
Think about how it relates to instant forces.
What does the impulse signify in dynamic systems?
Think about it in terms of earthquake forces.
True or False: The Dirac delta function is zero for all points except at zero.
Consider what happens to the function at various points.
Considering a structure that undergoes an impulse response due to an earthquake, calculate the impulse provided that the peak force experienced was 2000 N over 0.1 seconds.
Think about how impulse relates force and time.
Discuss how the response of a building to seismic waves can be modeled using the sifting property of the Dirac delta function and provide an example calculation.
Consider how impulses represent greater forces at specific time points in your model.
