Question

Suppose you exert 15 N on a machine, and the machine exerts 300 N on another object. what is the machine mechanical advantage?​

Answer 1

Answer:

M=20

Explanation:

Mechanical Advantage

It measures the force amplification achieved when we use a tool or machine that transmits the input force and applies a different force to another external device. If $F_a$ is the input force, and $F_b$ is the output force, then the mechanical advantage it

$\displaystyle M=\frac{F_b}{F_a}$

Note that if $F_b$ is greater than $F_a$, then the mechanical advantage will be greater than 1. It's less than $F_a$, M will be less than one

We are given $F_a=15\ N,\ F_b=300\ N$

$\displaystyle M=\frac{300}{15}=20$

It means that every newton applied to the input will be amplified to 20 N
