it applies torque to fulfill its design capabiities
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.

Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
Mechanical advantage=load/effort
The mechanical advantage of a screw can be found by dividing the circumference of the screw by the pitch of the screw. In this case, the total mechanical advantage is equal to the circumference of the simple machine to which the effort force is applied divided by the pitch of the screw.
The mechanical advantage of a screw is given as MA = circumference / pitch. The pitch of the screw is the number of threads per centimeter. The circumference is measured at the working portion of the screw, not the head.

Ideal Mechanical Advantage can be found using this formula IMA = DE / DR . Ideal Mechanical Advantage is a theoretical calculation, AMA,Êactual mechanical advantage is calculated with this formula, AMA = R / Eactual .
A screw is an inclined plane wrapped around a shaft. The inclined plane is a simple machine that offers the user a mechanical advantage. The shaft is what transmits a torque to that advantage.

Holding the diameter of the screw constant, closely spaced threads (fine pitch) have a higher mechanical advantage than thread which are spaced farther apart (course pitch). Mechanical advantage is the ratio of travel of the applied force to the ratio of the imparted force. Because the screw must rotate more times to insert a given depth, fine pitch has a higher mechanical advantage.
An magnetized screwdriver is an advantage for an electrician because it means the screw will remain attached to the screwdriver meaning it will be easier to unscrew. Hope this helps ;)
2 x 3.14+ (number of screws) / number of threads
Even the best screws only have a mechanical advantage of twenty percent. Therefore, the screw is not a very efficient lifting device.

Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
