Question: 1 / 400

In a first class lever, where is the fulcrum located?

At one end

In the middle

In a first-class lever, the fulcrum is positioned in the middle, which creates a balance point that allows the lever to pivot. This design means that the effort applied on one side of the lever will effectively lift the load on the other side. A classical example of a first-class lever is a seesaw, where the center point allows for the two ends to move in opposite directions when weight is applied to one side.

In this arrangement, the location of the fulcrum is crucial because it determines how force and movement are distributed. By having the fulcrum in the middle, resources can be efficiently used, allowing for mechanical advantage in lifting or moving objects. Understanding this fundamental principle helps grasp the mechanics of levers and their applications in various practical scenarios.
