The torque delivered by a two-stroke engine is represented by: T = (1000 + 300sin2θ - 500cos2θ) N-m where θ is the angle turned by the crank from the Inner dead centre. The engine speed is 250 rpm.
The mass of the flywheel is 400 kg and radius of gyration 400 mm.
Determine (i) the power developed(ii) the total percentage fluctuation of speed (iii) the angular acceleration of flywheel when the crank has rotated thro' an angle of 600 from the Inner dead centre and (iv) the maximum angular acceleration and retardation of flywheel.
