a 1st class lever
there are 3 types of levers, 1st 2nd and 3rd class.
1st: fulcrum between effort and resistance
2nd:resistance between fulcrum and effort
3rd: effort between fulcrum and resistance
Fulcrum = a pivot point on a lever.
Effort = force applied on lever
Resistance = load
1st example:see-saw/scissors
2nd example:wheelbarrow/car door
3rd example:someone raking/ hockey stick being usued

CoachThe fulcrum represents the point at which the lever pivots or rotates. It is the point where effort and resistance forces interact to create movement or maintain balance in a lever system. By adjusting the position of the fulcrum, one can change the mechanical advantage and optimize the leverage between effort and resistance.

How are the 3 kinds of levers classified?
The three kinds of levers are classified based on the relative positions of the effort, the resistance, and the fulcrum. In a first-class lever, the fulcrum is between the effort and the resistance. In a second-class lever, the resistance is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the resistance.
What lever has resistance between the axis (fulcrum) and the force (effort)?
In a second-class lever, the resistance is between the axis (fulcrum) and the effort. Examples include a wheelbarrow or a nutcracker.
What lever has the resistance force between the effort force and the fulcrum?
In a lever, the resistance force is located between the effort force and the fulcrum. This setup creates a mechanical advantage that allows a smaller effort force to overcome a larger resistance force. The position and distance of the resistance force from the fulcrum determine the effectiveness of the lever system.
What lever has resistance between the axis fulcrum and the force effort?
A second-class lever has resistance between the fulcrum and the effort force. In this type of lever, the load is situated between the fulcrum and the effort, which allows for increased force output at the expense of distance traveled. Examples include nutcrackers and wheelbarrows.
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.
