 1) Turning moment diagram is a graph between Torque and crank radius Torque and Crank angle none of the above Force and crank radius

 2) The energy is stored in Flywheel in form of Kinetic energy Potential energy Electrical energy Heat energy

 3) The radius of Gyration (k) for Rim Type Flywheel having radius ‘r’ is given by k = 2r k=r/2 k=r k=r/3

 4) The coefficient of fluctuation of speed of Flywheel is given by (Note:N1 =Maximum speed, N2 = Minimum speed, N = Mean speed.) (N1-N2) x N (N1-N2)/N (N1+N2) x N (N1+N2)/N

 5) The Coefficient of fluctuation of energy of flywheel is given as (note: Emax = Maximum Kinetic energy of the Flywheel. Emin = Minimum Kinetic energy of the Flywheel ) (Emax + Emin) x Work done per cycle (Emax – Emin) x Work done per cycle (Emax + Emin)/Work done per cycle (Emax – Emin)/Work done per cycle

 6) In industries which electrical braking is preferred? Regenerative braking. Plugging. Dynamic braking. None of the above.
