    A fulcrum is a basic mechanical component that serves as a pivot point or support for a lever. It is a fixed point around which a lever rotates or balances. The concept of a fulcrum is based on Archimedes’ principle, which states that a lever can be used to multiply the force applied to it.

    In a simple lever system, the fulcrum is the point where the lever rests or is supported. It acts as the center of rotation and divides the lever into two arms: the effort arm and the load arm. The effort arm is the portion of the lever where force is applied, while the load arm is the segment where the resistance or load is located.

    The position of the fulcrum relative to the effort and load can determine the mechanical advantage of the lever system. If the fulcrum is closer to the load, it will require less effort to lift or move the load, resulting in a mechanical advantage. On the other hand, if the fulcrum is closer to the effort, it will require more effort to move the load, resulting in a mechanical disadvantage.

    The fulcrum plays a crucial role in the functioning of levers, allowing for the amplification or redistribution of force and enabling various applications in different mechanical systems and devices.
