Answer:
the mechanical advantage is approximately 3.75.
Explanation:
To find the mechanical advantage, we'll use the formula:
[tex]\[ \text{Mechanical Advantage} = \frac{\text{Radius of Wheel}}{\text{Radius of Axle}} \][/tex]
Given:
- Radius of the wheel [tex](\(r_w\)) = 30 cm[/tex]
- Radius of the axle [tex](\(r_a\)) = 8 cm[/tex]
We can substitute these values into the formula:
[tex]\[ \text{Mechanical Advantage} = \frac{30 \text{ cm}}{8 \text{ cm}} \][/tex]
[tex]\[ \text{Mechanical Advantage} = \frac{30}{8} \][/tex]
[tex]\[ \text{Mechanical Advantage} \approx 3.75 \][/tex]
So, the mechanical advantage is approximately 3.75.
