What is the primary purpose of a flywheel in a mechanical system?

The primary purpose of a flywheel in a mechanical system is to store energy and reduce fluctuations in engine power. This device functions by maintaining a consistent rotational speed, which helps to smooth out the delivery of power from the engine or motor. When there are variations in load or speed, the flywheel can either release stored energy or absorb excess energy, effectively acting as a stabilizer for the system.

By doing so, it enhances the overall efficiency and performance of the mechanical system, ensuring that the power delivery is more uniform and reliable. This is particularly important in applications where consistent power is crucial, such as in internal combustion engines, where the power output can vary due to the nature of the fuel combustion process.

While reducing vibrations, increasing speed, and facilitating heat dissipation are important aspects of mechanical design and operation, they are not the primary function of a flywheel specifically. The flywheel’s main role centers around energy storage and the stabilization of power delivery in mechanical systems.
