a machine has a mechanical advantage of 0.6. what force should be applied to the machine to make it apply…

Explanation:

Step1: Recall mechanical - advantage formula

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 $F_{in}$

We can rewrite the formula as $F_{in}=\frac{F_{out}}{MA}$.

Step3: Substitute given values

Given that $MA = 0.6$ and $F_{out}=600\ N$, then $F_{in}=\frac{600}{0.6}=1000\ N$.

Answer:

C. 1000 N
