Q7:- The variation of crank shaft torque of a four cylinder engine may be approximately represented by taking the torque as zero for crank angle 0° and 180° and as 225 N.m for crank angle 20° and 45° ,the intermediate positions of the torque graph being straight lines. The cycle is repeated every half revolution. The average speed is 600 rpm. Supposing that the engine drives a machine requiring a constant torque, determine the weight of the flywheel with radius of gyration 25 cm which must be provided so that the total fluctuation of the speed shall be one percent.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
