Question

If the input force on a simple machine is 2 N and the output force is 4 N, what is it’s mechanical advantage?

Answer 1

Mechanical advantage, m = 2

Step-by-step explanation:

Given that,

The input force on a simple machine,
`F_i=2\ N`

The output force on a simple machine,
`F_o=4\ N`

To find,

The mechanical advantage of the simple machine.

Solution,

The ratio of the output force to the input force of any simple machines is called its mechanical advantage. Its expression is given by the below formula :

`m=(F_o)/(F_i)`

`m=(4)/(2)`

m = 2

Therefore, the mechanical advantage of the simple machines is 2.

Answer 2

Step-by-step explanation:

Given that,

Input force on a simple machine, F = 2 N

The output force on a simple machines, F' = 4 N

The ratio of the output force to the input force of any simple machines is called its mechanical advantage. Mathematically, it is given by :

`m=(F')/(F)`

Putting the value of F and F' in above equation. We get :

`m=(4)/(2)`

m = 2

So, the mechanical advantage of the simple machines is 2. Hence, this is the required solution.
