Yo,
I'm doing an experiment write up for the young modulus. The value for the young modulus I got was far off from the true value, but I think this was expected.
What I want to know is the problems that can occur during a standard classroom experiment that could effect the results and the calculation of the young modulus.
Problems I've talked about so far:
- We took the diameter once at the start of the experiment, but the wire might not be uniform and its diameter may change during the experiment
- errors in reading, zero error, etc.
- errors with equipment used
There's another error about kinks in the wire, but I'm not sure how to word it..
Thanks in advance for any help =].
