The critical damping coefficient ($c_c$) for a simple spring-mass-damper system is a theoretical value that represents the minimum amount of damping required to prevent oscillation. It is calculated using the formula $c_c = 2\sqrt{mk}$, where $m$ is the mass and $k$ is the stiffness of the system.
A vibrating system consists of a mass of 50 kg, a spring with a stiffness of 30 kN/m and a damper. The damping that is provided is only 20% of the critical damping. Calculate critical damping coefficient. - (5) Question not attempted
