Define damping factor
Webdamping, in physics, restraining of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipation of … Webdamping occurs when the coefficient of x˙ is 2 n. The damping ratio α is the ratio of b/m to the critical damping constant: α = (b/m)/(2 n). The ODE then has the form (1) x¨+2α nx˙ …
