Explanation:
A lever is a simple machine that consists of a rigid rod or plank that pivots on a fixed point called the fulcrum. By applying force to one end of the lever, called the effort arm, you can generate a larger force at the other end of the lever, called the load arm. The distance between the fulcrum and the effort arm determines the mechanical advantage of the lever.
In the case of lifting a heavy box, the lever allows you to exert a smaller force over a greater distance in order to lift the load. By positioning the fulcrum closer to the load and applying the effort force on the longer effort arm, you can magnify the force and make it easier to lift the box. This reduces the amount of force needed compared to lifting the box directly, making the task more manageable.
Additionally, the lever allows you to lift the box while keeping the direction of the force the same. The force you apply on one end of the lever is transmitted through the lever to the other end, allowing you to lift the load in the same direction as the applied force. This is essential for lifting the box effectively and avoiding any unnecessary or awkward movements.
Therefore, the purpose of the lever in this situation is to reduce the force needed to lift the box while maintaining the direction of the force.
