Term1/15

What is the Ideal Mechanical Advantage when a screwdriver with a handle of radius 1.2 cm is used to remove a screw in the back of a computer and the screw moves out 0.20 cm on each turn

Definition1/15

There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.
