    Burst speed of rotating disk

    I am looking for the equations for hoop stress and radial stress in a rotating disk, to calculate the theoretical burst speed. I am not looking for the more complex empirical solutions having to do with fatigue, balance, vibration, temperature, etc... A link would be great. I googled, but...

    Theoretical burst speed of a disk

    This must be a fairly simple equation. I looked through my old physics textbooks from 30 years ago and couldn't find it. I tried to google it, but there is WAY too much information, and NO equations. -Michael www.sewellgeneralcontracting.com ALBANY TROY SCHENECTADY NY

    "Engineer" in New York State?

    A week ago I met with the Owner and the Engineer on site to discuss the working drawings for a residential addition. The Engineer agreed to have a set of working drawings ready for the Owner "in about a week". The Engineer introduced himself by saying "I AM AN ENGINEER". When the Owner...

    Empirical solution is best.

    Sometimes needless center of gravity calculations just waste time and hold up the progress of a job. The best course of action is to proceed with the project and make small corrections as necessary. Here is a good example... http://www.petgroomer.com/groomertalk/page31-tow.htm -Mike...
