Understanding Torque Vector Direction: The Right Hand Rule Explained

Click For Summary
SUMMARY

The discussion focuses on the application of the right hand rule in understanding torque vector direction. Participants emphasize the importance of correctly positioning the right hand, ensuring that the thumb aligns with vector r and the index finger with vector F. Proper finger orientation is crucial; the middle finger should extend outward from the page when applied correctly. Adjusting the vectors to start from the same point can enhance comprehension of the rule.

PREREQUISITES
  • Understanding of vector notation and representation
  • Familiarity with torque concepts in physics
  • Basic knowledge of three-dimensional coordinate systems

Hi,

I was looking at this picture. I can't seem to get the right hand rule to work. I put my thumb on vector r and my index on vector F. My middle finger points INTO the page!

Hello.

Are you sure you are using your right hand? My middle finger of the right hand points out of the page.
 
Don't just place your fingers over the vectors. Also make sure that your fingers point in the same direction as the vectors. It's OK to move the vectors around (as long as they don't turn or stretch/shrink) so that they start at the same spot. That might help since your fingers do start in a single spot (sort of) AKA your hand.
