mass , m = 3 kg, radius. r = 200 mm = 0.2 m, a = 110 = 0.11 m,b = 150 mm = 0.5, N1 = 240 rpm, x = 4 mm.
(i) Initial compressive force on the spring (s1) :
w.k.t. the centrifugal force at the minimum speed,
For minimum position we know that,
(ii) Stiffness of the spring (s) :
Fluctuation of speed, Cs
Maximum speed, N2 = 258.7 rpm
w.k.t. the sleeve is , x = (r2 - r1)(b/a)
Centrifugal force at the maximum speed,
For maximum position w.k.t.
Stiffness of the spring,
