inches.
a. What is the mechanical advantage of the wheel and
axle?

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,

So, the mechanical advantage of the wheel and  axle is 16.
