Lever

A lever is a simple machine consisting of a rigid beam or rod that pivots on a fulcrum. It can be used to amplify force or change the direction of a force. It helps us lift or move objects by applying less force over a greater distance. Levers make our daily tasks easier by amplifying our effort.

Load

The load in a lever refers to the weight being lifted or moved. It is the force that the lever is designed to overcome. The load is positioned on one side of the fulcrum while the effort is applied on the other. By manipulating the position of the load and the effort, levers can provide mechanical advantage and make it easier to move heavy objects.

Fulcrum

The fulcrum is the fixed point or axis of rotation in a lever. It determines the balance and stability of the lever. The position of the fulcrum influences the mechanical advantage of the lever system. By strategically placing the fulcrum, we can optimize the efficiency and effectiveness of the lever.

Mechanical Advantage

Mechanical advantage refers to the amplification of force provided by a lever. It is calculated by dividing the distance from the fulcrum to the input force by the distance from the fulcrum to the output force. A higher mechanical advantage means less force is needed to move a load.

Effort Force

The effort force is the external force applied to a lever to make it move or overcome resistance.

Load Force

The load force is the force exerted by the object being moved, lifted, or manipulated by the lever.
