Viscous damping occurs naturally when mechanical systems such as pendulums or guitar strings vibrate in air or water. Viscous damping is also exhibited by devices called dashpot. A typical dashpot consists of a piston moving in a cylinder filled with a viscous fluid, Movement of pistorn is opposed by fluid, which must either flow through small holes in piston or flow through a narrovw gap around piston. Devices such as door closers and shock absorbers are example of dashpots. Dashpot The free vibration of a mechanical system consisting of a mass, spring and damper is characterized by the following differential equation: Depending on the combination of mass (m), spring constant (k) and damping coefficient (c), we can have three distinct cases. Only one of these cases exhibit harmonic (oscillatory) motion and is called Under-damped free vibration. The under-damped solution to the above equation for a particular combination of m, k, and c and initial conditions is given by: X(t)0.455 e0.1t sin(3.146 t)
