a machine has a mechanical advantage of 5. what force should be applied to the machine to make it apply 3000…

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 the given values

Given that $MA = 5$ and $F_{out}=3000\ N$, we substitute these values into the formula: $F_{in}=\frac{3000}{5}$.

Step4: Calculate the input force

$F_{in}=600\ N$.

Answer:

B. 600 N
