Explanation:

The mechanical advantage of a machine is a dimensionless quantity defined as the ratio of the output force to the input force. It is given by the quotient of these values, which means that depending on the type of machine the mechanical advantage of a machine can be greater, less than or equal to 1.

Therefore, the statement is false.
