- First-class levers have the fulcrum placed between the load and the effort, as in the seesaw, crowbar, and balance scale. If the two arms of the lever are of equal length, as with the balance scale, the effort must be equal to the load. If the effort arm is longer than the load arm, as in the crowbar, the effort travels farther than the load and is less than the load.
- Second-class levers have the load between the effort and the fulcrum. A wheelbarrow is a second-class lever. The wheel's axle is the fulcrum, the handles take the effort, and the load is placed between them. The effort always travels a greater distance and is less than the load.
- Third-class levers have the effort placed between the load and the fulcrum. The effort always travels a shorter distance and must be greater than the load. A hammer acts as a third-class lever when it is used to drive in a nail: the fulcrum is the wrist, the effort is applied through the hand, and the load is the resistance of the wood. Another example of a third-class lever is the human forearm: the fulcrum is the elbow, the effort is applied by the biceps muscle, and the load is in the hand.

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.

Can you give me some examples of class 3 levers?

How are levers grouped into classes?
Levers are grouped into three classes based on the relative positions of the load, effort, and fulcrum. Class 1 levers have the fulcrum between the load and the effort. Class 2 levers have the load between the fulcrum and the effort. Class 3 levers have the effort between the fulcrum and the load.
How are levers grouped?
Levers are grouped into three classes based on the relative position of the effort, load, and fulcrum. Class 1 levers have the effort and load on opposite sides of the fulcrum, Class 2 levers have the load between the effort and fulcrum, and Class 3 levers have the effort between the load and fulcrum.
How many basic type of levers are there?
There are three basic types of levers: first-class, second-class, and third-class. These levers differ based on the placement of the fulcrum, effort, and load.
What kinds of simple machines that can be located in a teleporter?
There is no such thing as a teleporter in the star trek sense. If you mean a telehandler or crane, there will be pulleys and levers.
Is their a lever on a bike?
Yes. A bike will have several levers. The crank arms are levers, the brake levers are levers, the shifters are levers, the handle bar is a lever.
Where can you find levers and what kinds?
Levers can be found in various systems such as tools, machines, and human body. There are three types of levers based on the relative positions of the fulcrum, resistance, and effort: first-class lever, second-class lever, and third-class lever. Examples include seesaws (first-class), wheelbarrows (second-class), and shovels (third-class).
How are levers divided?
Levers are divided into three classes based on the relative positions of the input force, the fulcrum, and the output force. Class 1 levers have the fulcrum positioned between the input and output forces, class 2 levers have the output force between the input force and the fulcrum, and class 3 levers have the input force between the fulcrum and the output force.
