Here we don't always depend on the number but only the convenience of handling mechanically.
First class. Fulcrum in the middle (scissors)
Second class : Load is in the middle (nut cracker)
Third class: Power is in the middle (forceps)

What does the machanical advantage of a first-class lever depend apon?
The distance from the fulcrum to the effort.
A lever has an input arm 50 centimeters and an output arm 40 centimeters long what is the machanical advantage of the lever?
1.25
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
What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.

How is machanical advantage calculated for a third class lever?
Mechanical advantage: Class-I lever . . . can be any positive number Class-II lever . . . always less than ' 1 ' (and more than zero) Class-III lever . . . always more than ' 1 '
What are Useful facts and details of a first class lever?
Your arm can be considered a first class lever.
Which type of lever always increases mechanical advantage?
second class lever
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
What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
Is it possible for a first or second class lever to have a mechanical advantage less than one or for a third class lever to have a mechanical advantage greater than one?
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
Why does a class 3 lever does not have the same mechanical advantage of a class 2 and 1 lever?
because they are smaller than the level 3 that's why
What is the mechanical advantage formula for a 1st class lever?
fd=MA
