Question

suppose the mechanical advantage of a machine is 4 and the input force is 20 N. What is the output force?

Answer 1

Answer: The output force is 80 N.

Explanation :

It is given that,

Mechanical advantage of a machine is 4

Input force is 20 N

We know that the ratio of output force to the input force gives the mechanical advantage of a machine.

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

Where

F' is the output force

F is the input force

`F'=20\ N* 4`

F' = 80 N

So, magnitude of output force is 80 N.

Answer 2

Suppose the mechanical advantage of a machine is 4, and the input force is 20 N. What is the output force?

Answer is : 80 Newtons
