Answer 1

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

\[
\text{MA} = \frac{\text{Load}}{\text{Effort}}
\]

In your example, you have:

- Load = 360 N
- Effort = 60 N

Plugging in the values:

\[
\text{MA} = \frac{360 \, \text{N}}{60 \, \text{N}} = 6
\]

Thus, the mechanical advantage of the class 1 lever is **6**.

The correct answer is **d. 6**.
