Screw forces

WebbA screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines . The … Webb1. Screw (a helical surface surrounding a central cylindrical shaft) 2. A hollow pipe inside which the screw is placed. 3. A geared motor to turn the screw in this case. As the shaft turns, the bottom end pull up a volume of water or other liquid. This water will slide up inside the spiral tube until it finally pours out from the top of the tube.
