the difference is the position of the fulcrum. a first class lever has the fulcrum between the lode and applied force. a second class lever has the load between the fulcrum and applied force. A third class lever has the applied force between load and fulcrum. The load happens to be the thing that you are affecting in the system. On a seesaw the load and applied force changes as either kid goes up, but the lower kid is always the force and upper is the load with the fulcrum in the middle. this happens to be a first class lever. a second class lever could be a bottle cap opener with the fulcrum at the end the bottle cap(load) in the middle and you pushing (force) on the other. a third class lever are like tweezers with the fulcrum on the closed end, force is you pushing in the middle, and affected load is whatever you pick up. There are also compound levers like nailclippers, but by diagramming the whole system it should be pretty easy to discover that it is a first class lever. It's compund because of the use of a lever system

LaoThe difference between first, second, and third class levers lies in the relative positions of the fulcrum, effort, and load. In a first-class lever, the fulcrum is positioned between the effort and the load. In a second-class lever, the load is positioned between the fulcrum and the effort. In a third-class lever, the effort is positioned between the fulcrum and the load.

What is the difference between a first class and a second class lever?
The main difference between a first class and a second class lever is the relative placement of the effort, load, and fulcrum. In a first class lever, the fulcrum is positioned between the effort and the load. In a second class lever, the load is between the fulcrum and the effort. Examples of first class levers include a seesaw, while examples of second class levers include a wheelbarrow.
What characteristics distinguish levers as first class second class or third class?
The distinguishing characteristic of first-class levers is that the fulcrum lies between the effort force and the resistance force. Second-class levers have the resistance force between the fulcrum and the effort force. Third-class levers have the effort force between the fulcrum and the resistance force.
What are Second and third class levers differentiated by?
Second class levers have the load between the fulcrum and the effort (load-fulcrum-effort), while third class levers have the effort between the load and the fulcrum (load-effort-fulcrum). Second class levers provide mechanical advantage and are more efficient for lifting heavy loads, while third class levers provide a speed advantage but require more effort.
What is the class of wheel barrow in levers?
A wheelbarrow is an example of a second-class lever. In second-class levers, the load is located between the applied force (effort) and the fulcrum. In the case of a wheelbarrow, the load (the materials being carried) is situated between the wheel (fulcrum) and the handles (effort).
How are second and first class levers differentiated?
In a first-class lever, the fulcrum is located between the applied force and the load. In a second-class lever, the load is between the fulcrum and the applied force. Examples of first-class levers include a seesaw or scissors, while examples of second-class levers include a wheelbarrow or nutcracker.
