A flywheel is used to control the speed variations caused by the fluctuations of energy during each each cycle of operation. It acts as a reservoir of energy which stores energy during the period when the supply of energy is more' than the requirement and releases the energy during the period when the supply of energy is less than the requirements.

Flywheel
The correct statement regarding the flywheel is option 'A': The flywheel reduces the fluctuation of speed during a cycle for constant output load.
There are several functions and advantages of using a flywheel in mechanical systems. One of the main purposes of a flywheel is to store kinetic energy and release it when needed. This helps in stabilizing the speed of the system and reducing fluctuations during a cycle.
Importance of Flywheel
A flywheel is an essential component in many mechanical systems, especially in engines and other rotating machinery. Its main function is to control the speed and store energy during the power stroke of the system. The flywheel acts as a reservoir of energy, which can be used to maintain a constant rotational speed during the other phases of the cycle.
Reducing Speed Fluctuations
When a system experiences varying load conditions, the rotational speed of the prime mover tends to fluctuate. These speed fluctuations can have adverse effects on the operation and performance of the system. Here's how a flywheel helps in reducing these fluctuations:
1. Inertia: The flywheel has a large moment of inertia due to its mass and radius. This means that it resists changes in rotational speed due to its tendency to maintain its state of motion. The high inertia of the flywheel helps to dampen the speed fluctuations caused by varying loads.
2. Energy Storage: During the power stroke of the system, when the load is high, the flywheel absorbs excess energy and stores it in the form of rotational kinetic energy. This stored energy is then released during the other phases of the cycle when the load is lower. This helps to maintain a more constant speed and reduces the impact of load variations on the overall system.
3. Smooth Power Delivery: By reducing speed fluctuations, the flywheel ensures a more consistent and smooth power delivery to the output load. This is particularly important in applications where a constant speed is required, such as in generators or vehicles.
Conclusion
In summary, the correct statement regarding the flywheel is that it reduces the fluctuation of speed during a cycle for a constant output load. The flywheel achieves this by utilizing its inertia and energy storage capabilities to dampen speed variations caused by changing loads.
