I have 3 x Flywheels of equal dimensions but different weight eg a.400lbs b.800lbs c.2000lbs,which one will keep turning the longest? Or is there no difference?
pa5tabear said:Assuming the surfaces experiencing friction were the same (same frictional coeffiecient?), how much would the actual rotational friction differ due to different masses?
A flywheel is a mechanical device that stores rotational energy and helps to maintain a steady rotation in a machine. It works by using its mass and inertia to resist changes in speed or direction.
The size of a flywheel affects its performance by increasing the amount of rotational energy it can store. A larger flywheel will have a greater moment of inertia, which means it will resist changes in speed or direction more effectively than a smaller flywheel.
The type of flywheel that is better depends on the specific application. A solid flywheel is more durable and can store more energy, but a spoked flywheel is lighter and can reach higher speeds. It is important to consider the specific needs and constraints of the machine when choosing between these two types of flywheels.
The material of the flywheel can affect its performance in several ways. A heavier material will increase the moment of inertia and allow for more energy storage, but it may also increase the weight and size of the flywheel. A lighter material may allow for higher speeds, but it may not be as durable. The choice of material should be based on the specific needs and constraints of the machine.
The rotational energy and performance of a flywheel can be calculated using the formula E = 1/2 * I * ω^2, where E is the energy, I is the moment of inertia, and ω is the angular velocity. The moment of inertia can be calculated by multiplying the mass of the flywheel by the square of its radius. The angular velocity can be measured or calculated based on the speed of rotation.
