5. A wheel is used to turn a valve stem on a water valve.
The wheel radius is 4 inches and the axle radius is .25
inches.
a. What is the mechanical advantage of the wheel and
axle?

Respuesta :

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.
