Question

you apply 100.0 N of force to a machine. The machine applies 20.0 N of the force to the load. what is the mechanical advantage of the machine

Answer 1

Mechanical advantage is 5
100/20

Answer 2

Answer:

The mechanical advantage of the machine 20%

Explanation:

Given that,

Output force = 20.0 N

Input force = 100 N

We need to calculate the  mechanical advantage of the machine

Using formula of mechanical advantage

$MA = \dfrac{F_{out}}{F_{in}}\times100$

Put the value into the formula

$MA=\dfrac{20.0}{100}\times100$

$MA=\dfrac{1}{5}\times100$

$MA=20\%$

Hence, The mechanical advantage of the machine 20%.
