Cables, wires and other similar contraptions are a staple in the modern industrial world. There is hardly any product that does not utilize a single cable. Bikes use them for brakes, as well as cars. Even communication systems use them. You may have seen the installation of telephone and even internet cables. Television companies also utilize these in the form of network cables. All machines, big or small, have cables with Push Pull Mechanical Controls inside the vast loop of wires and such inside their hulls.
They are usually seen by the public as two smaller wires that are bonded together, either twisted or braided, to come up with a single but much more stronger one. This technique was first done by sailors. Back then, there were no big and thick ropes for use in ships and other marine vessels. To substitute for this need, they have gotten hold of the biggest ones they could find and twisted them all together, ending in a far more superior line that just fits the bill.
Perhaps the people saw how strong the new ship rope was that they used the very same principle in other fields which are completely off tangent to nautical aspects. In the world of heavy equipment, they are known as wire ropes. These wire ropes are used for hauling, lifting and any other form of conveying force through tension.
Electrical engineers borrowed the idea from old sailors to come up with a tool of their own. These came to be known as optical cables. The name is obviously derived from the optic fibers inside each wire. These fibers are highly receptive to and can transmit electric signals within a short distances between the origin to recipient. These are not advisable for power transmission for longer gaps than a few kilometers. For such cases, power suppliers make use of a high voltage cable or a special power line.
They are also used for networking. In areas where only one equipment is to be shared by many, twisted pairs, coaxial and fiber optics are used. These are great in work environments where people use only one scanner, fax machine, and printer to carry out individual tasks.
The twisted pair has the subcategories. These are known as the shielded, unshielded, and foil pairs. In this type, the forward and return conductors are twisted together, hence, the name. This is made to cancel out electromagnetic interference from other pairs and all kinds of external sources. This is most commonly used for a family of local area networks at home and in the corporate setting.
The second classification is more or less similar as to those used in electrical engineering. The fiber optic type has a glass core center. This core is surrounded by layer after layer of protective material. The last and outermost layer is commonly made out of PVC or Teflon. It is much more expensive than the first classification, but it can effectively transmit data over longer spans due to its higher bandwidth.
There is also the coaxial classification, which people all know as the TV cable. They are extensible and can be bent at even the most odd positions. They keep electromagnetic transmissions safely within cables to assure of fast and reliable signals.
Push pull controls are also known as Bowden cables, named after the man who first thought of making them. They are found in every type of automobile, from bikes to loaders and other huge vehicles. They transmit force without requiring much too much effort from the operator. These can even be modified and custom made to suit every type of need.
