τ = r x F
Where:
* τ (tau) is the moment of force or torque, a vector quantity measured in Newton-meters (Nm).
* r is the position vector from the axis of rotation to the point where the force is applied. It is a vector quantity measured in meters (m).
* F is the force applied, a vector quantity measured in Newtons (N).
* x represents the cross product of vectors.
Explanation:
* Magnitude: The magnitude of the torque is given by: τ = r * F * sin(θ), where θ is the angle between the force vector and the position vector.
* Direction: The direction of the torque is perpendicular to both the force and the position vectors, following the right-hand rule.
Key points:
* Moment of force is a rotational equivalent of force in linear motion.
* It measures the tendency of a force to cause an object to rotate around an axis.
* The greater the distance from the axis of rotation (r) or the greater the force (F), the greater the moment of force.
