Question

i need help on robert hook

i just need someone that has actually carried out the experiment and knows something about the method/evaluation and the conclution btw this is for a private research and i dnt have the time for any sarcasm and stupid remarks thank you i need all the help i can get ! :D

Thanks in advance

Answer 1

Robert Hooke proposed hooke's law, which says that any force on a spring is directly proportional the the strength of the spring constant (K) and the displacement for which it under goes (delta X). The force acts as a restoring force, so it is given a negative sign, meaning its acts to return the spring to its normal point.

F= - (K) (Delta X)

Answer 2

I depends on the actual experiment that you carried out. I used to get my students to carry out the extension of a spring ( disposable) past its elastic limit. This can also be done with a fairly thin elastic band.

A graph is then plotted of extension against load. The graph will be a straight line until it reaches the elastic limit ( so obeying Hookes Law)- after that point the graph becomes a curve  as the extension is no longer proportional to load.
