Q2. Flywheel used in a engine
Ans. 
A flywheel is a mechanical device used in engines to store rotational energy and smooth out fluctuations in engine speed.
• Flywheels are typically made of steel or aluminum and are attached to the engine's crankshaft.

• They store energy during the power stroke and release it during the compression stroke to keep the engine running smoothly.

• Flywheels are also used in hybrid vehicles to store energy from regenerative braking...read more
