Question

The mechanical advantage of a machine is always greater than 1.
TRUE OR FALSE

Answer 1

false fam

Step-by-step explanation:

did the test

Answer 2

Answer: False

Step-by-step explanation:

The Mechanical Advantage (
`M_(A)`) of a machine is an adimensional quantity defined as the ratio of the output force
`F_(out)`and the input force
`F_(in)`:

`M_(A)=(F_(out))/(F_(in))`

It is important to note that
`M_(A)` can be equal to 1, greater than 1 or less than 1:

-When
`F_(out) = F_(in)`,
`M_(A)=1`

-When
`F_(out) > F_(in)`,
`M_(A)>1` This type of machines make task easiers

-When
`F_(out) < F_(in)`,
`M_(A)<1`
