Hey guys.
This is my first time posting here so go easy!
My group at uni has just been given an assignment to determine Young's Modulus and the Yield Stress of grey PVC, we have to make our own testing machine and record the results with a 95% or greater statistical confidence. Just curious has anyone here done this before, or can lend me a hand with some ideas on a way to actually test it? The PVC pipe can also either be a grey electrical conduit or as a rectangular strip. Also the length has to be accounted for, but we're not too sure whats the best lenth to go for. Any help would be greatly appreciated so thanks alot.

i think a long length would be good so the extension would be appreciable. Actually i think the length is up to you, just use the one that is the easiest for you, keep it simple.
all the best for your experiment!
