Each bearing type has its own limiting speed. The theoretical speed that bearings can run at safely, even if heat generation by internal friction occurs, is called the maximum permissible speed. The permissible speed is related to bearing type, type of cage, lubricant type, load and cooling conditions to which the bearing is subjected  For contact rubber seals(2RS type), the permissible speeds are limited by the peripheral velocity of the seal lip.  Normally, this is approximately 50 - 60% of that of non-contact rubber seals. If light contact rubber seals are required, this must be stipulated with the order. If high loads occur, the permissible speed values must be reduced and the following supplementary factors applied, except under standard operating conditions(Cr/P<12, Fa/Fr>0.2 )  COMPENSATION FOR MAXIMUM PERMISSIBLE SPEED DEPENDENT ON LOAD RATIO   Cr/P 5 6 7 8 9 10 11 12 COMPENSATION FACTOR 0.72 0.79 0.85 0.90 0.93 0.96 0.98 1.00 COMPENSATION FOR MAXIMU

CAT 2011 takers can fill up the CAT 2011 online registration form via following link:  https://iim.prometric.com/  . The website is being operated by Prometric (the company that conducts GRE in India and assigned the work to conduct online CAT). There is a guide available which helps you understand how to fill the CAT online registration form. You can look at it here:  http://www.catiim.in/pdf/reg_guide.pdf  (PDF). Pagalguy.com has reported that there are several errors in the online registration form. Few of them are - The STD code has been labelled as 'Country' code. Address Line 1 does not accept more than 30 characters, making it very difficult to enter correct address. Also, it does not accept any special character.

science goes as bad... Whether or not this is actually scientifically possible doesn’t matter. The main idea behind any science fiction just has to be believable within the parameters of the world in which it is set. Indeed, the director of the new  Planet of the Apes  movie, Rupert Wyatt, has said he found the explanation of the original 1960s films – that the apes evolved naturally after being domesticated by humans – unsatisfying. Some people might find it odd to talk about science fiction needing plausible explanations. The clue is there in the name – science  fiction . And there are probably plenty of people who dislike the entire genre because it inevitably includes unrealistic elements. But really it’s an issue that extends to all fiction. As George Bernard Shaw supposedly put it, you are allowed one big lie and everything else must be logical. Perhaps you can even get away with a few lies, but ask too much of the audience and it all becomes too distracting to accept even the b

 welcome to the series of C programming tutorials I request not to post questions or anything in this thread, as it will only disrupt the flow and co-ordination of the tutorials. OK everyone, this tutorial is basically designed for programmers, basically new to computing or new to "The C-Language". So now let us get started with the C. History of C  C language was developed by Dennis Ritchie in early 70s at the Bell Laboratories for Unix operating system. C is a procedural language. C was influenced by B, ALGOL, FORTRAN and Assembly. C influenced most of the modern world programing languages which include the mighty C++ and Java as well. Above points are enough to answer the most common questions asked in vivas (oral-examinations) or objectives. p.s : These tutorials will be based on DevC++ IDE and on Windows platform you can download DevC++ from here  http://www.bloodshed.net/index.html

MECHANICAL error was the cause of death of a young Namibian pilot in May this year at the Hosea Kutako Intentional Airport, the final report on the incident has found. The investigation into the death of Tiaan Oberholzer (21), a Desert Air pilot on May 22, has determined the cause of the accident was due to a "broken left hand magneto ground wire". In the final report issued this month, the Directorate of Aircraft Accident Investigations at the Ministry of Works and Transport, stated that Oberholzer "decided to do a final walk around inspection" after he had loaded four passengers into the Cessna 210 aircraft. He was due to fly the passengers on a safari flight to Doro Nawas and other tourism destinations. The report notes that when the aircraft was parked at the tarmac, Oberholzer decided to do the final walk around inspection and "without knowing that the left hand magneto ground wire was broken, he manually rotated the propeller resulting in a pre-detonatio
