To calculate the mechanical advantage (MA) of the wheel and axle, you can use the formula:
\[
\text{MA} = \frac{\text{radius of the wheel}}{\text{radius of the axle}}
\]
Given that the radius of the wheel is 15 cm and the radius of the axle is 2.5 cm, we can plug in these values:
\[
\text{MA} = \frac{15 \, \text{cm}}{2.5 \, \text{cm}} = 6
\]
Therefore, the mechanical advantage of the wheel and axle is **6**.
The correct answer is **b) 6**.
\[
\text{MA} = \frac{\text{radius of the wheel}}{\text{radius of the axle}}
