Which formula represents torque?

The formula for torque is given by T = Fd, where 'T' represents torque, 'F' is the force applied, and 'd' is the distance from the pivot point to the point where the force is applied (often referred to as the lever arm). This relationship indicates that torque is the product of the force exerted and the perpendicular distance to the line of action of the force.

In practical terms, if you apply a force at a distance from a pivot, you create a rotational effect. The greater the force or the longer the distance from the pivot, the larger the torque produced. This is a fundamental principle in mechanics, particularly in situations involving rotational motion, such as turning a wrench or opening a door.

The other formulas do not correctly express this relationship. For example, dividing force by distance or adding the two components does not represent the concept of torque, which is inherently linked to the multiplication of force by distance. This helps clarify why the chosen formula accurately describes the nature of torque.
