    Another question on shaft critical speed

    Greg, I sent the company an email and they acknowledged that the input window was unclear (and to me it was misleading). I did get proper information for running the program for multiple spans. And thanks, also, for the equation. I was confusing the "whirl" which Alexit referred to for...

    Another question on shaft critical speed

    Greg, I think you are correct. With regard to the input the program gives a data base for shape selection (and it is a structural program, not mechanical for shafts), when one selects the shape it inputs the moment of intertia, Young's modulus, and provides the uniform weight per foot. Then I...

    Another question on shaft critical speed

    Thanks, Greg and Alexit for two very helpful answers. Being a retired engineer my studies in dynamics and vibrations were more years in the past than I care to admit.[pipe] So, forgive if I ask what to you is the obvious. Alex, I believe your clue has to do with the natural frequency of the...

    Another question on shaft critical speed

    I find in technical books an literature that computation of critical speed deals with a shaft with two supports and one or more rotating masses attached to the shaft. In dealing with design of a line shaft where one only has torsional loads (plus the weight of the shaft for shear and...

    Depth of frost line in central Alabama

    New member here. I'm trying to find the depth of the frostline in central Alabama. I have purchased a copy of the ICC Code and have been unable to find it there. Also the texts and references I have from college days to not provide it. Help is appreciated...thanks, Oakley
