Question

Which of the following is used to store energy and give up whenever required?
1. Clutch
2. Gear
3. Governor
4. Flywheel

Answer 1

Correct Answer - Option 4 : Flywheel

Explanation:

Flywheel:

• A flywheel is used to control the speed variation caused by the fluctuations of energy during each cycle of operation.
• It acts as a reservoir of energy that stores energy during the period when the supply of energy is more than the requirement and releases energy during the period when the supply of energy is less than the
• It does not control the speed variations caused by the varying load.

Governor:

• Governor regulates the mean speed of an engine when there are variations in the load.
• It controls the mean speed of an engine by controlling the fuel entry to the engine.
• Governor has no influence over cyclic speed fluctuation.

Clutch:

• It is used to engage and disengage Engine or driver shaft to the driven shaft without stopping the prime mover i.e. Engine.
• It is used to obtain temporary connection between driver and driven shaft.

Gear:

• Gears are rotating machine elements that transmit torque from one shaft to another via the teeth machined into them.
• Gear is positive drive machine element i.e. slip is not possible.
• A no of gear pairs are used to obtain different speeds and torque as per requirement.
