referrence of physics laws in my experiment
I've got a SAC which is my own experiment. The experiment is measure the Sag in a supported beam (A.K.A putting weights on top of a flexible ruler supported at both ends and measuring how much the ruler bent)
Since i have to make referrence to law's and elaborate how these laws are imposed on the ruler, which of these following laws/methods should i make a mention of?
- Hooke's law (Not sure)
- Newton's third law (I think yes)
- Elastic potential energy (?)
- is it safe to say the ruler is in equilibrilum?
here is a few pictures showing my experiment. Hopefully you can all grasp the visual concept of my experiment from these.
Anything else i should make mention of?
any help would be greatly appreciated.
