Calculating deflection of a tube

  1. Jun 30, 2010 #1
    I'd like to calculate the maximum deflection a PTFE tube of 65mm diameter and 5mm thickness. The tube is roughly 3m long and a 1.3m section will be unsupported, I want to know what the maximum deflection the end will experience under it's own weight. I've looked up it's tensile stength which is betweem 10-40 MPa (I don't really understand that unit though)

    Could anyone help with this?

    Btw, this is not a homework problem this is for a real application.

    Treat it like any other beam. Roark's is a good reference for the appropriate formula.
