      Hey there its my first blog hope you guys will enjoy it.

      First of all what is suspension..?? Its a basic unit which connects a vehicle to its wheel and provides a relative motion between them. It can be springs, dampers, struts, shock absorbers etc. 

      In this blog I am gonna talk about basics of suspension. The first question is why do we need suspension..?? The basic need of suspension is to satisfy three basic needs which I call the three C  namely comfort, control, contact.(I have copied it)

      We need to be comfortable while driving. Suppose there are stones or pebbles or other things on the road that can cause serious bumping of your vehicles so this makes driving uncomfy.

      The second and most important thing is contact. While driving tires need to be in contact with the ground or it ​can be hell of a dangerous.

      The third and most important thing which comes with contact is the control. 

      Now the basic suspension is a spring. Its very simple it just stores energy and releases and are very common with independent suspension. The springs which we use in suspension are either coil spring which we use in independent suspension. The second type of spring is the leaf spring which we can see in trucksdownload.thumb.jpg.6a6938d26b5f5f5d63a81download_(1).thumb.jpg.a9e2182965baacbcd.

      What spring does that it stores energy  from the motion of the force pushing into it when compressed and releases when it expands.

      The drawback is that it will bounce back your car every time the energy releases. So it does not find much use accept in solid wheel axle.

      The second type which we are gonna discuss are the dampers. Dampers consist of a cylinder with piston fitted into it. Piston has small holes and the cylinder is filled with oil. It basically converts the kinetic energy of shock into other form of energy generally the heat energy. The good thing about dampers is that it reacts to velocity which means that if there is a smaller bump it will dampen less and when the jerk is very large it will dampen more. Moreover it shows reactions to turning, braking and accelerations also.download_(2).thumb.jpg.23612c477925e8133

      Now the main and most used component that's struts. It is a combo of spring and a damper. You know what's the best thing about struts it doesn't only act as a suspension it also act as a basis structural component as it eliminates the need of upper control arm and ball joint(except for wishbone strut which has upper control arm).download_(3).thumb.jpg.7129b20110ffca6d8

      Now last but not the least the tire has also some spring and damping properties.

      Hope you guys have enjoyed reading this. Next time I will explain MacPherson struts

      Cheers

    2. A team researchers used a promising new material to build more functional memristors, bringing us closer to brain-like computing. Both academic and industrial laboratories are working to develop computers that operate more like the human brain. Instead of operating like a conventional, digital system, these new devices could potentially function more like a network of neurons.
      Researchers are always searching for improved technologies, but the most efficient computer possible already exists. It can learn and adapt without needing to be programmed or updated. It has nearly limitless memory, is difficult to crash, and works at extremely fast speeds. It's not a Mac or a PC; it's the human brain. And scientists around the world want to mimic its abilities.

      "Memristors could be used as a memory element in an integrated circuit or computer," Hersam said. "Unlike other memories that exist today in modern electronics, memristors are stable and remember their state even if you lose power."

      Current computers use random access memory (RAM), which moves very quickly as a user works but does not retain unsaved data if power is lost. Flash drives, on the other hand, store information when they are not powered but work much slower. Memristors could provide a memory that is the best of both worlds: fast and reliable. But there's a problem: memristors are two-terminal electronic devices, which can only control one voltage channel. Hersam wanted to transform it into a three-terminal device, allowing it to be used in more complex electronic circuits and systems.
