Answer 1

To find the mechanical advantage (MA) of a lever, you can use the formula:

\[
\text{Mechanical Advantage (MA)} = \frac{\text{Distance from Effort to Fulcrum}}{\text{Distance from Load to Fulcrum}}
\]

In this case, the distance from the effort to the fulcrum is 15 meters, and the distance from the load to the fulcrum is 5 meters.

Plugging in the values:

\[
\text{MA} = \frac{15 \, \text{meters}}{5 \, \text{meters}} = 3
\]

So, the mechanical advantage is **3**.

The correct response is **3**.
