SUMMARY

The discussion centers on determining the appropriate size and weight of a flywheel needed to produce a torque equivalent to 200kg or resist a force of 200kg. A user suggested a flywheel with a circumference of approximately 500mm, weighing around 40kg, and spinning at 3000 RPM. However, the responses clarified that 200kg represents mass, not torque or force, and emphasized that a flywheel's torque is dependent on its angular momentum and the rate at which it is decelerated. Accurate calculations require a clear understanding of the relationship between mass, torque, and angular momentum.

PREREQUISITES
  • Understanding of angular momentum and its relation to torque
  • Familiarity with rotational dynamics and flywheel design
  • Basic knowledge of mass and force concepts in physics
  • Proficiency in using calculators for mechanical engineering applications
NEXT STEPS
  • Research the principles of angular momentum and its calculation
  • Learn about the design and specifications of flywheels in mechanical systems
  • Explore the relationship between mass, torque, and force in rotational systems
  • Investigate the use of online calculators for mechanical engineering problems
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in designing or analyzing flywheel systems and rotational dynamics.

Homework Statement
Hello,

https://www.fxsolver.com/solve/

I am using this calculator to figure out how large/heavy a flywheel I need to produce torque of 200kg, or that could resist a force of 200kg applied to it.

I am not proficient in mathematics, so my terms or what I'm asking might be not phrased correctly. My gut instinct is it would be apprx. 500mm circumference with a weight of perhaps 40kg? These of course can vary to match the torque needed.The motors I'm intending to use are 3000rpm or 50 rotations a second.



Thankyou.

I'm afraid your question as asked does not make sense.
First, 200kg is a mass, not a torque nor a force (though some use "kg weight" for a force).
Secondly, a given flywheel rotating at a given rate does not provide a specific torque. It provides angular momentum. The torque you get from it depends on how quickly you try to stop it.
Perhaps if you provide full details of what you are trying to do we will be able to assist.
