WebThe resulting equation is similar to the force equation for the damped harmonic oscillator, with the addition of the driving force: − k x − b d x d t + F 0 sin ( ω t) = m d 2 x d t 2. 15.27. When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of the oscillator is known as transients.
