What quantities are required to calculate torque?

To calculate torque, the necessary quantities include the magnitude of the force applied, the distance from the fulcrum (the pivot point) to the point where the force is applied, and the angle at which the force is exerted relative to the lever arm. This is because torque is generated when a force causes rotational motion around a fulcrum.

The formula for torque (τ) is given by τ = r × F × sin(θ), where r is the distance from the fulcrum to the point of force application, F is the force applied, and θ is the angle between the direction of the force and the line from the fulcrum to the point of force application. This means that both the distance and the angle are critical factors in determining how effectively a force can create rotation about a fulcrum.

Understanding how these components interact allows for precise calculations of torque, which is essential in various engineering and physics applications where rotational motion is involved. In contrast, the other options mentioned do not incorporate the necessary elements for torque calculation.
