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
The 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.

Class levers have the resistance force between the effort force and the fulcrum?
Class 2.
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 is the lever which the effort force is between the resistance force and fulcrum?
This is a second-class lever. The resistance force is located between the effort force and the fulcrum in this type of lever. An example of a second-class lever is a wheelbarrow.
In what order do the effort fulcrum and resistance appear on a second class lever?
On a second class lever, the effort is applied at one end of the lever, while the resistance is located in the middle of the lever, between the effort and the fulcrum.
Where is fulcrum effort and resistance on a broom?
where your hand is, your lower hand is the fulcrum.
What does the machanical advantage of a first-class lever depend apon?
The mechanical advantage of a first-class lever depends on the relative distances between the effort force, the fulcrum, and the resistance force. The mechanical advantage is calculated as the ratio of the distance from the fulcrum to the effort force to the distance from the fulcrum to the resistance force.
In what class of a lever is the effort between the fulcrum and the resistance?
In a class 1 lever, the fulcrum is located between the effort (input force) and the resistance (output force). Examples of class 1 levers include seesaws and scissors.
What type of lever is a punch?
A punch is considered a third-class lever, where the effort is applied between the fulcrum and the resistance. In this case, the hand acts as the fulcrum, the knuckles provide the effort, and the object being punched is the resistance.
