im having bother writing the conlcusion for hookes law experiment, can any one help or point me in the right direction ????
I recently finished my first course in mechanics (or maybe I should call it physics course A, however...) but we also talked a bit about Hooke's Law. Unfortunately my teacher wasn't a "real" teacher in physics (actually he was a teacher of Mechanical engineering) and it doesn't look like we learnt the "real" Hooke's law, can anyone explain to me what this is then in simple terms?:
σ = Eε
My teacher told us that this (^) was hooke's law. A quick look on wikipedia shows F=-kx, but also I can find σ = Eε if I scroll down a bit.
I know that sigma is the stress caused on a certain area (like the area of the cable holding up an elevator), E is the elastic modulus of a certain material, and epsilon, umm I don't know the word for it in english but I know what it is. :)
Thanks in advance.
