A vibratory system consists of a mass 12.5 kg, a spring of stiffness 1000N/m , and a dash-pot with damping coefficient of 15 Ns/m.The value of critical damping of the system is Correct Answer 223.6 Ns/m

Given m= 12.5 kg, k= 1000N/m, c= 15 Ns/m Critical Damping, cc = 2m√k/m = 2√km On substituting the values, we get cc = 223.6 Ns/m.

A centrifugal clutch has four shoes. When the clutch is at rest, each shoe is pulled against a stop by a spring so that it leaves a radial clearance of 10 mm between the shoe and the rim. The pull exerted by the spring is then 700 N. The mass centre of the shoe is 150 mm from the axis of the clutch.
