Show hintHide hint
Remember the definition of the Dirac delta function.
Question 2.
What does the integral of δ(x) over the entire real line equal?
Show hintHide hint
Consider the area under the curve.
3Question 3.

Show hintHide hint
Consider the area under the curve.
Question 5.
Consider a bridge where a car passes over it at time t = 0, producing a load represented by δ(t). How would you use the Dirac delta function to analyze the effect on the bridge's structure?
Show hintHide hint
Think about how the impulse behaves over time.
Question 6.
A concentrated load P is applied at point x = a along a beam described by the differential equation. How would you set up the governing equation including the Dirac delta function?
Show hintHide hint
Focus on how to represent point loading mathematically.
