A screw axis (helical axis or twist axis) is a line that is simultaneously the axis of rotation and the line along which translation of a body occurs. Chasles theorem shows that each Euclidean displacement in three-dimensional space has a screw axis and the displacement can be decomposed into a rotation about and a slide along this screw axis.. Plcker coordinates are used to locate a screw A 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 most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside. The screw passes through a hole in another object or medium with threads on the inside of the hole that Architectural Linear Bar Grilles & Registers.
