Homework Help: Strain Gauge Placement on Cylinder

  1. Sep 29, 2009 #1
    1. Problem Statement: I am trying to measure the radial (#s 3-6) and hoop (#s 1, 2, 7, 8) strain (and from that, stress) present in an aluminum cylinder. I am trying to use a standard full wheatstone bridge setup, but am having trouble settling on a setup that would give me an accurate measurement. I haven't tried my current setup yet as I want to be reasonably sure that it will work before using my given materials since they are relatively limited. Can anyone offer any constructive criticism or help?

    2. Relevant equations: N/A

    3. The attempt at a solution: see attached picture

    Also, I forgot to mention that the cylindrical system is a shrink-fit system, with dimensions as shown in the picture. One of my main problems is trying to compensate for the gradient imposed by the boundary between the surfaces.
