Assertion (A): In designing the size of the flywheel, the weight of the arms and the boss are neglected.
Reason (R): The flywheel absorbs energy during those periods when the turning moment is greater than the resisting moment.
Explanation:
- The flywheel is an important component in machines that involve rotational motion, such as engines and turbines. It is designed to store and release rotational energy to ensure smooth operation and reduce fluctuations in speed.
- The size of the flywheel is determined based on various factors such as the desired energy storage capacity, the speed variation limits, and the power requirements of the machine.
- The weight of the arms and the boss of the flywheel refers to the additional mass present due to the arms (spokes) and the central hub (boss) of the flywheel. These components add to the overall weight of the flywheel.
- In the design process of the flywheel, the weight of the arms and the boss is generally neglected. This is because their contribution to the overall energy storage capacity of the flywheel is relatively small compared to the rim mass.
- The rim mass of the flywheel is the main factor that determines its energy storage capacity. The rim mass is the mass distributed along the outer circumference of the flywheel, where most of the energy is stored.
- The energy absorption and release capability of the flywheel is crucial for its functioning. During periods when the turning moment (input torque) is greater than the resisting moment (output torque), the flywheel absorbs energy and stores it in the form of rotational kinetic energy.
- When the turning moment becomes smaller than the resisting moment, the flywheel releases the stored energy to overcome the resistance and maintain the rotational motion of the machine.
- The flywheel acts as a reservoir of energy, absorbing and releasing energy as required, to ensure smooth operation and minimize speed fluctuations in the machine.
- Therefore, both Assertion (A) and Reason (R) are individually true. The weight of the arms and the boss is neglected in the design of the flywheel, and the flywheel does absorb and release energy during periods when the turning moment is greater than the resisting moment.
- Furthermore, Reason (R) is the correct explanation of Assertion (A) as it explains the purpose of the flywheel in absorbing and releasing energy to maintain smooth operation.
Reason (R): The flywheel absorbs energy during those periods when the turning moment is greater than the resisting moment.
