angular acceleration) of the fly wheel.[Answer: (1) 251 kW, (2) 0.81%, (3) 7.95 rad/sec²] Problem (5): A four-stroke cycle engine develops 18.38kW at 250 rpm. The turning moment diagram is triangular for expansion stroke. The turning moment for expansion (i.e., working) stroke is 2.8 times that of the compression stroke. Neglecting the work done during suction and exhaust stroke and assuming constant torque, determine the moment of inertia of the flywheel to keep the total fluctuation of speed within 1.0% of the mean speed. Problem (6): [Answer: 1693.3 kg.m²]
