Screw Pitch is defined as the axial distance between threads. One complete revolution of the screw will move it into an object the distance of the pitch. The smaller the pitch, the greater the mechanical advantage (ability to do work) achieved.

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 determined by comparing the distance traveled along the screw's threads to the force applied to turn the screw. It is calculated as the ratio of the circumference of the screw to the pitch of the screw thread. A higher mechanical advantage indicates that less force is needed to lift a load.
The mechanical advantage equation for a screw is calculated by dividing the circumference of the screw (distance traveled per revolution) by the pitch of the screw (vertical distance traveled per revolution). The formula is MA = 2πr / p, where MA is the mechanical advantage, r is the radius of the screw, and p is the pitch of the screw.
It converts electricial enargy into meachanical enargy
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.
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 ;)
You divide the pitch of the jack's screw into a length equal to the distance traveled by the end of the Jack's lever around the circumference of a circle having a radius equal to the jack's lever. Elliott
The IMA (ideal mechanical advantage) of a screw is determined by the ratio of the circumference of the screw head to the pitch of the screw thread. The formula for calculating IMA is 2πr/p, where r is the radius of the screw head and p is the pitch of the screw thread.
Mechanical advantage for the six simple machines are: Lever: Mechanical Advantage = Length of Effort Arm / Length of Load Arm Pulley: Mechanical Advantage = Number of ropes supporting the load Wheel and Axle: Mechanical Advantage = Radius of Wheel / Radius of Axle Inclined Plane: Mechanical Advantage = Length of Incline / Height of Incline Wedge: Mechanical Advantage = Length of Sloping Side / Thickness of Wedge Screw: Mechanical Advantage = Circumference of the screw / Pitch of the screw
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.
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 .
