4'5 Dirac Delta Function

4.5 Dirac Delta Function
Unit Impulse Mechanical systems are often acted
on by an external force of large magnitude that
acts only for a very short period of
time. Examples 1- A vibrating airplane wing
could be struck by lightining
2- baseball, tennis ball could be sent soaring
when struck violently.
