To find the mechanical advantage (MA) using the given formula, you can use the radii of the wheel and the axle.
Given:
- Radius of the wheel = 49 cm
- Radius of the axle = 7 cm
Now, plug the values into the formula:
\[
MA = \frac{\text{Radius of Wheel}}{\text{Radius of Axle}} = \frac{49 \text{ cm}}{7 \text{ cm}} = 7
\]
So the mechanical advantage is **7**.
