Cam and Follower Mechanical Notes

Image
  WELCOME to PKmindworld, Here  are proper notes of (KOM) subject - topic Cam and follower.                 Cam and Follower Cam-   Cam is a rotating mechanical part used to provide rotating, reciprocating or oscilating motion to other part attached with it.   this other part is called follower. the easy example is shown in  diagram.                  cam & follower figure.                1) Cams are widely used in automatic machines, IC engines for open or closing the valves. 2) Cams & follower make point contact between them (as shown above)  therefore they come in Higher pair.    basically the main function of cam follower in IC engines is to control the inlet & outlet valves, in easy language the procedure of supplying fuel or ejecting gas from piston cyclinder is done with the help of cam & follower.  or it can be used in other machines where oscilation and reciprocating mechanism is required.

Time Traveling Part 0 "Begin the Journey"

       Universe has infinite possibilities    As we see the night sky, stars, sun and moon. we observe and feel their presence and then we start thinking about it, many Question comes in mind, that how they are made how they all works systematic, how universe made and how its work ?  When we start thinking  some of our thoughts end up as the earth atmosphere ends, while some of our thoughts goes beyond in Universe geometry, its dimensions its working and super nova, Black holes, Galaxies etc.                 Johannes Kepler Scientist like Copernicus, Kepler, Galileo, Newton, Einstein change the way of our thinking about the universe. All the scientist gave us lot of laws and scientific concept in different fields, which help us to relate all concepts and to think forward. Its depend on our self, that how we use this laws and principles,  either to pass exams  OR  to discover something new. As science & Technology geowth, we started thinking beyond the

Time Traveling part 1 the "days equation"

Universe have infinite possibilities                                                             (((( ( Introduction )))))   An equation by solving which we can calculate total time travel by a time traveler as he goes in past or in future.  According to our current technology it is not possible to travel in past, but many scientist gave their concepts and theories and many problems and paradoxes are seen like, nobody can travel faster than speed of light according to Einstein theory of relativity, Grand father paradox and generation of other Paradoxes, curved space time and gravity etc. So, now we starting our first Research output of  Research in time traveling Journey. its  " The Days Equation " on Nov, 2014                      Time Traveling             Its very easy to understand. Just a simple addition and subtraction.             ((((( equation ))))    Total time =  T[2n + d]    (days equation) here, T = time period(sec, hour,
