Answer 1

The mechanical advantage (MA) of a lever can be calculated using the formula:

\[
\text{Mechanical Advantage} = \frac{\text{Length of effort arm}}{\text{Length of load arm}}
\]

In your case:

- Length of effort arm = 6 m
- Length of load arm = 3 m

Now, substituting these values into the formula:

\[
\text{Mechanical Advantage} = \frac{6 \, \text{m}}{3 \, \text{m}} = 2
\]

Thus, the mechanical advantage of the lever is **2**.
