Answer:
To provide a pivot point around which the lever rotates, enabling the lever to lift or move a load.
Step-by-step explanation:
The fulcrum is a fixed point around which a lever rotates or pivots. The function of the fulcrum in a lever is to provide a pivot point for the lever to rotate around, enabling the lever to lift or move a load.
In a lever, there are three main components: the load, the effort, and the fulcrum. The load is the object being lifted or moved, the effort is the force applied to the lever to lift or move the load, and the fulcrum is the fixed point around which the lever rotates.
The position of the fulcrum in a lever determines the mechanical advantage of the lever. The mechanical advantage is the ratio of the load force to the effort force, and it is determined by the distance between the fulcrum and the load and the distance between the fulcrum and the effort. The closer the load is to the fulcrum, the less effort is required to lift it, but the load will not be lifted as high. The farther the load is from the fulcrum, the more effort is required to lift it, but it will be lifted higher.
