This characteristic is essential to the vast majority of its uses. In most applications, the lead of a screw thread is chosen so that friction is sufficient to prevent linear motion being converted to rotary, that is so the screw does not slip even when linear force is applied, as long as no external rotational force is present. The mechanical advantage of a screw thread depends on its lead, which is the linear distance the screw travels in one revolution. Their rotation raises or lowers the two long vertical threaded shafts - as they are not free to rotate. Through mechanical advantage this eventually causes the horizontal bevel gears (at far left and far right, with threaded center holes) to rotate. The operator rotates the small vertical bevel gear in the center. Helical structure used to convert between rotational and linear movement or force Screw thread, used to convert torque into the linear force in the flood gate.
