    PVC Pipe Elastic Modulus?

    I'm trying to find out the elastic modulus of a PVC I have. I'm making and instrument out of it and I need to know the modulus to determine the fundamental frequency. Can someone tell me what the modulus would be for a D-3034 SDR-35 Pipe. I know that the pipe stiffness is 46psi. How do I...

    Resonant frequency calculation

    Yes, I am confusing Force pounds with mass pounds. This is exactly my problem, thanks! That's what I get for learning only the metric system all the way through school and using and American for development efforts. This information is really helpful for me to determine the dimensions for my...

    Resonant frequency calculation

    I'm trying to do a calculation for a Cantilever beam using PVC. I'm using the Formula that Tom Irvine pointed out however I'm having some issues with Units.. Units are as follows... E=lb/in^2 I=in^4 rho= lb/in If I use the formula this gives me the square root of in^3. Can someone help me...
