Suppose the surface of that end face is defined as Datum A, and that the axis of the cylinder is defined as Datum B by using a datum callout on the diameter. Also, suppose one side of the off-center slot is...

    Oil filled vibration damper

    What is the best way of designing an oil filled vibration damper ? The frequency range of concern is perhaps 30-80Hz, at low amplitude (0-.001"). Should such a damper utilize a relatively long viscous restriction or is a short orifice good enough ? According to my edition of the Vibration...

    Columbia Tragedy

    Does anyone know the current status of the Columbia investigation ? I saw some time ago that they had physically simulated the foam impact and found that it could have penetrated the wing. I recall reading that an engineer had done a study during the flight, using a "spreadsheet", and...

    Visual Basic v Fortran

    For programs (or parts of programs) that can be written using either, is there really any difference in speed between compiled VB and Fortran ? I know some developers write VB programs and call Fortran routines from them, but is this really necessary ? Is it really just because they have...
