Examples of Class 2 levers include: Wheelbarrow Crowbar Nut cracker Wheelbarrow is Class 2 lever Class 3 lever A Class 3 lever has the effort between the load and the fulcrum. Both the effort and load are in the same direction. Note that the length of the load arm goes all the way to ...
The Class of Lever is determined by the location of the load, fulcrum, and force. In a Class Two Lever, the Load is between the Force and the Fulcrum. The closer the Load is to the Fulcrum, the easier the load is to lift. Examples include wheelbarrows, staplers, bottle openers, nut ...

Class 2 levers: The resistance comes between the input force and the fulcrum, such as in a wheelbarrow or bottle opener. Class 3 levers:The fulcrum is on one end and the resistance is on the other end, with the effort in between the two, such as with a pair of tweezers. ...
1. First-class lever: In a first-class lever, the fulcrum is located between the force and the load. This type of lever can either amplify force or increase distance, depending on the placement of the fulcrum. Examples of first-class levers include seesaws and scissors. 2. Second-class ...
Class 3 Levers: The fulcrum and the load are located on the opposite sides of the lever. The effort is applied between the load and the fulcrum. The examples are a broom, a human arm, and a fishing rod. In the third-class levers, the mechanical advantage is always less than one and...
