I think I am getting some concepts confused, so i need help clarifying the answers to the following questions:
1. can you use a rubber band instead of a steel spring in a scale to measure weight?
- I said no, because it would break
2. Should the wires supporting a suspension bridge be elastic or inelastic?
- I said elastic so that it can return to its original position, but I don't know how to expand on this...
3. How is a steel wire "very elastic" if it does not stretch much with large forces?
- I am not sure at all about this oneAnd k is independent of gravity right? (i.e., if you have a force and a displacement on earth, would those be in the same proportion on the moon? I'm thinking F/x = k equals a direct proportion but I might be breaking smoe rules).
I spent a good hour before and that is the progress I have made.
