Third class:
Fulcrum is the condyles, effort is the masseter muscle, and load is whatever you're chewing on.

How is a hammer pulling out a nail a 3 class lever?
A hammer is a 3rd class lever. A third class lever has a load-effort-fulcrum configuration. What is interesting about a hammer is that though the load is the head of the hammer, the effort and the fulcrum are both in the hand. What makes it a 3rd class lever is that the effort is more in the hand and fingers, while the fulcrum is closer to the base of the hand at the wrist.
Is a crowbar a lever or a fulcrum?
A crowbar is a Class 1 lever (fulcrum or pivot in the middle) The trick to remembering which type is which is: FRE 123. If F the fulcrum is in the middle it's Class 1, if the Resistance (or load is in the middle (a wheelbarrow) it's Class 2 and if the Effort is in the middle (tweezers) it's Class 3.It's a class 1 lever because the curve part of the crowbar (the fulcrum) is in between the effort, at the end of the crowbar where your hands are, and the load side, the short side that pry's the thing open.
Why is the can opener a second class lever?
because the load is situated between the effort and fulcrum
What class lever is a spoon?
It is a third class lever machine because The effort is in between the load(food) and the fulcrum(handle)
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
Where are the effortloadand fulcrum located in a first class lever?
In a First Class lever, the fulcrum is between the effort and the load.
Where are the effort load and fulcrum locate in a first class lever?
The fulcrum is between the effort and the load.
What is between a fulcrum and effort force?
It depends on which type of lever you are using. If it is a Class II lever then the load is between the fulcrum and the effort.
How are second and first class levers differentiated?
A First Class lever is one in which the fulcrum is locatedbetween the effort and the load.A Second Class lever is one in which the load is locatedbetween the fulcrum and the effort.A Third Class lever is one in which the effort is locatedbetween the fulcrum and the load.
In what class of a lever is the effort between the fulcrum and the resistance?
Class 3.
What class of lever are ice tongs?
Ice tongs are actually third class lever. In a third class lever, the effort is between the fulcrum and the load.
What is the MA of a first class lever?
It is (distance from fulcrum to effort)/(distance from fulcrum to load).
When is the effort force decreased in a first class lever?
The effort-to-load force in a first class lever is decreased when the distance between the effort and the fulcrum is less than the distance between the fulcrum and the load.
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
Why is tiptoe a second class lever?
Because a second class lever is a lever in which the resistance is located between the fulcrum and the effort. When you stand on your tiptoes, the fulcrum is located at your toes, the effort is at your Achilles tendon, and the resistance is the weight of your body pushing down. therefore, the resistance is between the fulcrum and the effort.
Where is the lever of the hammer?
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.
What is the law for a second-class lever?
the law for a second class lever is that the load is between the fulcrum and the effort
