I am trying to understand how to calculate the torque on a flywheel. If I have a 90 pound flywheel that is 20" in diameter, how do I find the torque?
Thanks for your help. :rofl:

Conservation of energy always applies. Assuming the flywheel is perfect, the energy you can get out of it would be exactly equal to the energy you put into it.Can this flywheel provide it's stored energy more than the crank's when release ?

Welcome to PF... first you'll need more information about the performance requirements of the flywheel. Hopefully what you read in this thread will help you understand why that is: torque is only one component of the performance of the flywheel. You also need to know how long you want it to be able to generate that torque and probably at what minimum rpm (giving you energy and power).yusufk said:I have to design a flywheel to generate 30 ft lb torque. How do i go about it?
Torque is a measure of the force that causes an object to rotate around an axis. It is calculated by multiplying the force applied to an object by the distance from the axis of rotation to the point where the force is applied.
To calculate the torque of a flywheel, you will need to know the weight of the flywheel (in this case, 90 lbs) and the radius of the flywheel. Multiply the weight by the radius to get the torque in pound-feet. For example, if the radius is 2 feet, the torque would be 180 pound-feet (90 lbs x 2 feet = 180 pound-feet).
Torque is important for a flywheel because it determines the rotational speed of the flywheel. The greater the torque, the faster the flywheel will rotate. This is important for machines that use flywheels for energy storage or to maintain a constant speed.
Torque is typically measured in pound-feet (lb-ft) or Newton-meters (Nm). Pound-feet is used in the United States, while Newton-meters is used in most other countries.
Yes, torque can be increased or decreased by changing the amount of force applied to an object or by changing the distance between the force and the axis of rotation. For a flywheel, increasing the weight or the radius will increase the torque, while decreasing either will decrease the torque.
