Aug 08, 2020 · A first-class lever has the axis (fulcrum) located between the weight (resistance) and the force (figure 1.21 a). An example of a first-class lever is a pair of pliers or scissors.The difference between first, second and third class levers lies in the relative positioning of three items. Pivot diagram of a Class 2 lever. Different classes of levers are identified by the way the joint and muscles attached to the bone are arranged. For the Class 2 lever the load is between the pivot and the effort (like a wheelbarrow). The effort force needed is less than the load force, so there is a mechanical advantage. The first class lever is the one that uses a fulcrum in between, and the applied force and load are at opposite ends. If we look at the diagram the first diagram shows the fulcrum in centre and load and force on each end. Load is always lifted by applying force so in the diagram E shows the force and R might be showing the load which is lifted.
