01What is Torque?

  • Torque, denoted by the symbol τ or T, is a measure of the tendency of a force to cause an object to rotate around an axis.
  • It is defined as the product of the force applied perpendicular to the lever arm and the distance from the axis of rotation to the point where the force is applied.
  • In other words, torque is the rotational equivalent of force in linear motion.

02Torque Calculation Formula

  • The formula to calculate torque is given by:
  • τ = F * r * sin(θ)
  • Where:
  • τ is the torque
  • F is the perpendicular force applied
  • r is the lever arm distance
  • θ is the angle between the force and the lever arm

03Step-by-Step Guide to Calculating Torque

  • Identify the force applied to the object. Determine the magnitude and direction of the force.
  • Determine the lever arm distance, which is the perpendicular distance between the axis of rotation and the point of force application.
  • Measure the angle between the force vector and the lever arm vector. This angle is crucial for calculating torque accurately.
  • Substitute the values into the torque formula: τ = F * r * sin(θ)
  • Calculate the torque using the formula.
  • Make sure to use consistent units throughout all calculations.
  • Pay attention to the direction of the torque, as it indicates the rotational direction.
