👋 Hello! I'm Alphonsio the robot. Ask me a question, I'll try to answer.

what is the formula for rotational forces?

The formula to calculate the torque generated by a force applied perpendicular to the radius is:




With :

  •  is the torque expressed in newtons-meters [N.m]
  •  is the force expressed in newtons [N]
  •  is the radius expressed in meters [m], note that  , the length of the OP segment.
