Levers Pulleys Mar 9 2022 nbsp 0183 32 Greek mathematician Archimedes was the first to develop lever principles in 260 B C A lever system consists of four parts beam fulcrum load and effort Beam A plank
Levers work by reducing the amount of force required to move an object or lift a load The lowered amount of effort needed is compensated through increased distance over which the force has to be applied A lever is that mechanical device which is mainly found responsible for amplifying the input force in order to provide a greater output force which is intended to provide leverage The ratio of the output force to that of the input force is termed as the mechanical advantage of the lever

Dec 10 2024 nbsp 0183 32 Leverage is another mechanical benefit achieved in a system It is ideal for transporting or lifting objects that are hefty There are numerous examples of this practical simple machine The seesaw crowbar fishing line oars wheelbarrows and garden shovel are all effective examples of levers Jul 23 2025 nbsp 0183 32 Levers are commonly used to amplify or redirect force allowing for easier movement or manipulation of objects Levers are of three types first class levers second class levers and third class levers Before proceeding to types of levers let s learn terms related to levers Terms related to lever are discussed below
According to where the load and effort are located with respect to the fulcrum there are three types or classes of lever This is a type of lever which has the fulcrum in between the weight and the force applied Its order is represented as force fulcrum weight This is the most basic type of lever Example Lever simple machine used to amplify physical force All early people used the lever in some form for moving heavy stones or as digging sticks for land cultivation
