Question

1. suppose the mechanical advantage of a machine is 4, and the input force is 20 n. what is the output force? (1 point) 80 n 16 n 5 n 24 n

Explanation:

Step1: Recall the formula for mechanical advantage

The formula for mechanical advantage ($MA$) is $MA=\frac{F_{out}}{F_{in}}$, where $F_{out}$ is the output force and $F_{in}$ is the input force.

Step2: Rearrange the formula to solve for $F_{out}$

From $MA = \frac{F_{out}}{F_{in}}$, we can get $F_{out}=MA\times F_{in}$.

Step3: Substitute the given values

Given that $MA = 4$ and $F_{in}=20\ N$. Then $F_{out}=4\times20\ N$.

Answer:

$80\ N$
