Question

You apply 100.0 N of force to a machine. The machine applies 20.0 N of force to the load. What is the mechanical advantage of the machine?

Answer 1

This machine has a mechanical advantage of 1/5, 20%, or no realistic advantage. This is because the machine transferred 80 N into external systems of the original 100 N applied.

Hope this helps!

Answer 2

Answer:

0.20

Explanation:

The mechanical advantage of a machine is given by:

$MA=\frac{F_{out}}{F_{in}}$

where

Fout is the output force (the load)

Fin is the input force (the effort)

For this machine, the input force is 100.0 N, while the output force is 20.0 N, so the mechanical advantage is

$MA=\frac{20.0 N}{100.0 N}=0.20$
