3 cards from this section. Quick, good the night before a test.
What is the primary property of the Dirac delta function at points other than zero?
Think about where an idealized point load would have no effect.
What does the Dirac delta function represent?
Consider how forces can be applied in reality.
What is the integral of the Dirac delta function over the whole real line?
Think about the properties of a function that is only active at one point.
True or False: The Dirac delta function is a regular function.
Remember its key characteristics compared to regular functions.
A structure is subjected to a point load represented by δ(x-3) and is vibrating due to dynamic forces. If the natural frequency is 5 Hz, derive the equations of motion using the delta function.
Use the properties and definition of the Dirac delta function.
Explain how you would methodically solve a differential equation representing a beam deflection subjected to a dynamic point load using the Dirac delta function.
Approach it stepwise, applying the properties you've learned!
