What is the definition of torque in the context of levers?

Torque, in the context of levers, is defined as the rotational force that is applied around a pivot point or fulcrum. It is calculated by taking the product of the force exerted on the lever and the distance from that force to the pivot point. This relationship illustrates how both the amount of force and the distance from the pivot affect the ability to cause rotation. A greater distance or a larger force will result in a larger torque, making it easier to lift or move an object. This demonstrates the principle of leverage, where a small amount of force applied further from the pivot can be more effective than a larger force applied closer. Understanding this concept is crucial in various applications of physics, such as engineering and mechanics, where levers are extensively used.
