Detailed Video Concept and solution
Levers are classified into three types or class based on the position of load and effort on the fulcrum;
Class 1 Lever:
- A Class 1 lever has the fulcrum placed between the effort and load
- The movement of the load is in the opposite direction of the movement of the effort
- E.g. crowbars, scissors, pliers, tin snips and seesaws
Class 2 Lever
- A Class 2 lever has the load between the effort and the fulcrum
- In this type of lever, the movement of the load is in the same direction as that of the effort
- E.g. nutcrackers, wheelbarrows, doors, and bottle openers
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
- E.g. tweezers, arm hammers, and shovels
