7. An Archimedean screw is a screw within a closely fitting cover, so that water can be raised when the
screw is turned. Suppose the screw has a mechanical advantage of 12.5. If the screw is turned several times, so
that the input distance is 15.7 m, how much has water been lifted upward by the screw?

Respuesta :

The height through which the water is lifted is 196.25 m.

What is mechanical advantage?

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.

Mechanical advantage is also defined as the ratio of output force to input force in a system.

Mechanical Advantage = Output force / input force

12.5 = output force / 15.7

output force = 15.7 x 12.5

output force = 196.25 m

Thus, the height through which the water is lifted is 196.25 m.
