Torque depends on

Torque depends on Correct Answer Force and moment arm

The correct answer is option 3) i.e. Force and moment arm

CONCEPT:

  • Torque: Torque is the turning effect produced on an object due to a force acting on it at a distance from a fixed point. The object tends to turn about this fixed point.
    • It is defined mathematically as the cross product of force and the perpendicular distance to an axis of rotation.

Consider a fore F acting at a distance r from a fixed point O as shown.

The torque produced is given by:

τ = r × F = rFsinθ 

 
  • The SI unit of torque is N-m.

EXPLANATION:

  • Torque is the cross product of force and perpendicular distance to an axis of rotation.
  • The moment arm of a force system is the perpendicular distance from a fixed point to the line of action of the force.
  • Therefore, torque depends on force and moment arm.
