How to work out frictional torque and resisting motion

Click For Summary
SUMMARY

This discussion focuses on calculating frictional torque and resisting motion in a system where a mass is suspended from a flywheel. The key formulas required for these calculations include the torque equation τ = r × F, where τ is the torque, r is the radius of the flywheel, and F is the force due to gravity acting on the mass. Additionally, understanding the relationship between angular acceleration and linear acceleration is crucial for determining the resisting motion as the mass falls. The conversation references a related thread for further exploration of these concepts.

PREREQUISITES
  • Understanding of basic physics concepts such as torque and angular motion.
  • Familiarity with the equations of motion, particularly those involving gravity.
  • Knowledge of the relationship between linear and angular acceleration.
  • Ability to apply Newton's laws of motion in rotational systems.
NEXT STEPS
  • Research the formula for calculating torque in rotational systems.
  • Study the relationship between linear acceleration and angular acceleration.
  • Explore the concept of moment of inertia and its impact on rotational motion.
  • Learn about energy conservation principles in mechanical systems involving friction.
USEFUL FOR

Students and professionals in physics, mechanical engineering, and anyone interested in understanding the dynamics of rotational systems and frictional forces.

how to work out "frictional torque" and "resisting motion"

Hi there,
if I have a scenario were a Mass is suspended from a flywheel. If the mass is released from rest and falls a distance in an amount of time.

how would i work out the
frictional torque
and resisting motion

does anyone know what formulas i would need.

help would be much appreciated



thanks a lot
