JACKSCREWS Meaning and
Definition
-
Jackscrews are mechanical devices that are primarily used for lifting or applying force to heavy loads. They consist of a threaded rod or screw and a corresponding nut or plate. The threaded rod is usually made of metal and is equipped with a screw-like groove that runs along its length, allowing it to engage with the threads of the nut or plate. This threaded connection enables the jackscrew to convert rotary motion into linear motion.
Jackscrews typically have a handle or lever attached at one end of the threaded rod, allowing the user to rotate it and therefore control the lifting or pushing action. These devices are often employed in applications where a significant amount of force is needed in a controlled and precise manner, such as in construction, engineering, automotive, or aerospace industries.
The concept behind jackscrews is based on the principle of a screw and nut mechanism, which utilizes the inclined plane formed by the threads to multiply force. By turning the handle or lever, rotational motion is transformed into axial movement, causing the nut or plate to move along the threaded rod. The mechanical advantage provided by jackscrews enables heavy objects to be lifted, positioned, or compressed with relative ease.
Jackscrews come in various sizes and designs to accommodate different load capacities and application requirements. They are commonly used in conjunction with other mechanical systems, such as gears or pulleys, to further amplify their lifting or force-generating capabilities.

Etymology of JACKSCREWS
The word "jackscrews" is a compound noun, combining "jack" and "screws".
The word "jack" has a long history and can be traced back to Middle English, where it originally referred to a mechanical device used to lift heavy objects. This sense of "jack" comes from the Old French word "jaque" or "jaques", which meant a mechanical contrivance or a type of pulley. The term likely originated from the name Jacques, which was a common French given name during that time.
On the other hand, the term "screws" originates from Middle English as well, derived from the Old French word "escroue" meaning a cylindrical screw. This French term ultimately came from the Latin word "scrofa", which referred to a sow or pig.
