Question

In the 1800s, a German prince designed a hand-cranked machine to lift water from a

stream to the kitchen window. The machine required 200 N of effort force to lift
980 N of water: What is the mechanical advantage of the prince's machine?

Answer 1

Mechanical advantage = 4.9

Step-by-step explanation:

Given:

Effort required to lift the water is,
`\textrm{Effort}=200\ N`

Load of water that is lifted is,
`\textrm{Load}=980\ N`

We know that, mechanical advantage of a machine is obtained by dividing the load by effort force.

Therefore, mechanical advantage is given as:

`MA=\frac{\textrm{Load}}{\textrm{Effort}}\\\\MA=(980)/(200)\\\\MA=4.9`

Therefore, the mechanical advantage of the prince's machine is 4.9.
