Acantilever can be considered as a mass, spring, damper system.

(a) is this a first, second, or third order system, and why? list the energy storage elements and associated energy storage mechanisms.
(b) assuming the system is underdamped, what output would you expect from this system when subject to a step input? roughly sketch your answer
