A turning moment is the combined effect of the angular displacement and the angular acceleration of an object undergoing rotational motion. It provides a quantitative measure of how these two quantities are related and how they affect the object's rotational motion.
In the context of flywheels, the turning moment is directly related to the rotational inertia of the flywheel and its angular acceleration when a force is applied to it. The angular inertia of an object represents its resistance to changes in rotational motion, while the angular acceleration refers to the rate of change of an object's rotational angular velocity.
When a force is applied to a flywheel, it causes the flywheel to rotate around an axis through the center of its mass. The turning moment of the force is the product of the force applied and the distance from the axis of rotation through the center of mass.
The turning moment required to cause a specific angular acceleration in a flywheel is directly proportional to the product of the force applied and the radius of the flywheel. This means that increasing either the force or the radius will result in a higher turning moment required to achieve the same angular acceleration.
In other words, increasing the force applied to a flywheel increases the turning moment required to cause the same rotational acceleration. Similarly, increasing the radius of the flywheel decreases the turning moment required to achieve the same rotational acceleration.
For example, if a flywheel is rotated with a force of 10 N applied 0.2 m from the center of mass, it will have a turning moment of 4 Nm. This means that to achieve the same rotational acceleration, the force would need to be increased to 15 N
