Re: [PSUBS-MAILIST] Acrylic formula ?

["Jason Ness" <nessjj@eckerd.edu>]

    This is what I got from an engineering book, but it gives the wrong
answers, I use 8000 as allowable stress, I would love if one of the ME's out
there could tell me what is wrong with this formula.  PSI
=(2*thickness*allowable stress)/(outside radius)

thanks
Jason
