This isn't my friends...this is something i got off the internet, but unfortunately the only one i could find, and the masses used are too big. My friend's one had 0 0 0 0 for the first 5 loads' extensions!
Homework Statement
How would you define the ultimate tensile stress of rubber?
Homework Equations
If I had a force/extension graph of rubber, what point in the graph would show me the value of the ultimate tensile stress??
The Attempt at a Solution
Is it the same thing as ultimate...
Homework Statement
I was not in for the Young's Modulus of copper wire experiment, so a friend gave me their data. It seems very wrong and the graph will in no way give proportionality.
The Attempt at a Solution
Does anyone have data or results from old school days or anything at all...
