Mechanical Advantage

What does a Mechanical Advantage less than 1 indicate?

• It indicates that the machine requires more input force to lift a given weight.

• It indicates that the machine is highly efficient.

• It indicates that the machine can lift heavier weights with less force.

• It indicates that the machine is not functioning properly.
