Answer:
m = 16
Step-by-step explanation:
We have,
Radius of wheel is 4 inches and radius of axle is 2.5 inches. It is required to find the mechanical advantage of the wheel and axle. For a wheel and axle, the radius of wheel to the radius of axle is called its mechanical advantage. So,
[tex]m=\dfrac{\text{radius of wheel }}{\text{radius of axle}}\\\\m=\dfrac{4}{0.25}\\\\m=16[/tex]
So, the mechanical advantage of the wheel and axle is 16.
