The turning moment exerted on the crank shaft of the above engine is given by: T = 10,000 + 2000 sin 2 
– 1800 cos 2 . where is the crank angle measured from T.D.C. Assuming the load torque to be constant, determine
(i) the power of the engine when turning at 250 rpm.
(ii) the moment of inertia of the flywheel if the speed variation from the mean speed is not to exceed ± 0.25%.
(iii) the angular acceleration of the flywheel for = 450.
