The mechanical advantage MA of a screw is defined as the ratio of axial output force Fout applied by the shaft on a load to the rotational force Fin applied to the rim of the shaft to turn it. For a screw with no friction (also called an ideal screw), from conservation of energy the work done on the screw by the input force turning it is equal to the work done by the screw on the load force: WebPut a 2 foot diameter handwheel on it and your hand moves 75 inches for every revolution (circumference). That means you get a force multiplication of 600:1 (the ratio of 75 and 1/8th inches). Therefore, 17 lbs of force on a 1 foot handle ( 2 foot handwheel) attached to a screw with a thread pitch of 8 results in 5 tons of force.
