What is the principle behind the functioning of a lever? (2019)
Step 1: Understand that a lever is a simple machine that helps lift or move heavy objects.
Step 2: Identify the three main parts of a lever: the fulcrum (the pivot point), the load (the object being lifted), and the effort (the force applied to lift the load).
Step 3: Learn that the lever works by balancing the load and the effort around the fulcrum.
Step 4: Realize that when you apply a small effort on one side of the fulcrum, it can lift a larger load on the other side.
Step 5: Understand that this is called mechanical advantage, which means using less force to move something heavy.
