Question

A resistance force is 173 N and the AMA is 3.2. What is the effort force?

Group of answer choices

54 N

0.1 N

4 N

554 N

Answer 1

To find the effort force (EF) using the Actual Mechanical Advantage (AMA), you can use the following formula:

\[
\text{AMA} = \frac{\text{Resistance Force (RF)}}{\text{Effort Force (EF)}}
\]

Given that the resistance force (RF) is 173 N and the AMA is 3.2, rearranging the formula to solve for the effort force gives:

\[
\text{EF} = \frac{\text{RF}}{\text{AMA}}
\]

Substituting the values:

\[
\text{EF} = \frac{173 \, \text{N}}{3.2} \approx 54.0625 \, \text{N}
\]

Since we are rounding and considering the answer choices, the closest value is:

**54 N**.
