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 '

Divide the Effort Distance (ED) by the Load Distance (LD) and this will give you the Mechanical Advantage (MA). MA=ED/LD

It's the same as for any other lever. MA = distance of load from fulcrum/distance of effort from fulcrum. The answer will be less than one.

What does the machanical advantage of a first-class lever depend apon?

The distance from the fulcrum to the effort.


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


Why is it useful to use a third class lever with the machanical advantage less then 1?

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)


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


How do you find the output force of a 1st class lever?

Multiply (the input force) x (the lever's mechanical advantage).
