The lever equation defines the forces and the physical features of a lever in its equilibrium status. It derives from the comparison of the torque acting on the lever: Fa × a = Fb × b where: Fᵢ are the forces, either the effort or the resistance; and lᵢ are the arms of the...
Class 1 has the fulcrum placed between the effort and load. Class 2 has the load between the effort and the fulcrum. Class 3 has the effort between the load and the fulcrum. Each has its own uses and advantages. Questions you may have include: ...
Types of Levers When using a lever to perform work, we focus not on masses, but on the idea of exerting an inputforceon the lever (calledthe effort) and getting an output force (calledthe loadorthe resistance). So, for example, when you use a crowbar to pry up a nail, you are ex...
