Introduction
A pendulum -mass structure is unique of the modest systems in physics to equally set-up
and to designate mathematically, high and mighty no friction or external forces. Though,
damping the pendulum -mass structure displays an undulation that is not as pretentious as an
undamped event. Below, the damped state of the pendulum -mass structure is reconnoitered.
