The moment of inertia of a flywheel is 6500 kg-m^2, from the turning moment diagram, it is found that fluctuation of energy is 56000 N-m, if mean speed is 120 rpm, find the minimum speed.
(a) 121
(b) 119
(c) 122
(d) 118
This question was addressed to me in final exam.
This interesting question is from Coefficient of Fluctuation of Speed topic in portion Turning Moment Diagrams and Flywheel of Machine Dynamics
