The equation of the turning moment diagram for the three crank engine is given by: T(N.m) =25000 - 7500 sin 3theta where θ radians is the crank angle from inner dead cen?tre. The moment of inertia of the flywheel is 400 kg-m2 and the mean engine speed is 300 r.p.m. Calculate the power of the engine and the total percentage fluctuation of speed of the flywheel, if 1. The resisting torque is constant, and 2. The resisting torque is (25 000 + 3600 sin θ ) N-m.

Question
The equation of the turning moment diagram for the three crank engine is given by: T(N.m) =25000 - 7500 sin 3theta
where θ radians is the crank angle from inner dead cen?tre. The moment of inertia of the flywheel is
400 kg-m2 and the mean engine speed is 300 r.p.m. Calculate the power of the engine and the total
percentage fluctuation of speed of the flywheel, if 1. The resisting torque is constant, and 2. The
resisting torque is (25 000 + 3600 sin θ ) N-m.
