6.2: Spring-Mass Problems (with Damping) - Mathematics …
In this section we consider the motion of an object in a spring–mass system with damping. We start with unforced motion, so the equation of motion is my ′′ + cy ′ + ky = 0. Now suppose the object is displaced from equilibrium and given an initial velocity. Intuition suggests that if the damping force is sufficiently weak … See more
We say the motion is underdamped if c < √4mk. In this case r1 and r2 in Equation 6.2.2 are complex conjugates, which we write as ω1 = √4mk − … See more
We say the motion is overdamped if c > √4mk. In this case the zeros r1 and r2 of the characteristic polynomial are real, with r1 < r2 < 0, and the general solution of Equation 6.2.1 is y = c1er1t + c2er2t. Again limt → ∞y(t) = 0 as in the underdamped case, but the motion … See more
We say the motion is critically damped if c = √4mk. In this case r1 = r2 = − c / 2m and the general solution of Equation 6.2.1 is y = e − ct / 2m(c1 + … See more
