SUMMARY

The discussion focuses on determining the direction of torque, specifically whether it is clockwise or counterclockwise. The key method mentioned is the corkscrew rule, which states that if you point the thumb of your right hand in the direction of the torque, your fingers will curl in the direction of rotation. This technique allows for a clear understanding of rotational direction based on the applied torque. It is emphasized that the perspective from which the torque is viewed affects the interpretation of its direction.

PREREQUISITES
  • Understanding of basic physics concepts, particularly torque and forces.
  • Familiarity with the right-hand rule in physics.
  • Knowledge of equilibrium conditions for objects.
  • Basic grasp of rotational motion principles.
NEXT STEPS
  • Study the application of the right-hand rule in various physics problems.
  • Explore advanced concepts in rotational dynamics.
  • Learn about torque calculations in different mechanical systems.
  • Investigate the effects of torque on equilibrium in static systems.
USEFUL FOR

Physics students, engineering students, mechanics, and anyone interested in understanding rotational motion and torque dynamics.

Hey guys,

I know how to do torque and forces for an object in equilibrium...but how do I know whether a torque is clockwise or counterclockwise?
 
Physics news on Phys.org
Often if you see in which direction the force acts you can find the direction of rotation. If not, and you only have the torque, you can use the corkscrew rule to find the direction of rotation. I.e. point the thumb of your right hand in the direction of the torque and then your fingers curl in the direction of rotation.

So the torque acts in the clockwise direction from a viewpoint that looks in the direction of the torque.
