These are, ∫ a+ε a−ε f (t)δ(t−a) dt = f (a), ε > 0 ∫ a − ε a + ε f ( t) δ ( t − a) d t = f ( a), ε > 0. At t = a t = a the Dirac Delta function is sometimes thought of has having an “infinite” value. So, the Dirac Delta function is a ...

WebOct 28, 2013 · Impulsive typically means a large force that is applied over a short period of time. The quantity ∫F dt is known, but the force and the time interval over which the force is applied is not known. In the extreme, an impulsive force truly is an impulse: A Dirac delta distribution.

However, given what I have written in the force function I would expect the driving force to become zero.
