Hi, I'm new round here and I hope you will forgive if this has already been asked. I've tried searching extensively, but can't quite find it. I found something very similar though, which I'll include. It is common knowledge that if you stretch a rubber band it warms up. Does this also apply to stretching or extending a spring (within the elastic limit)? If so, I read somewhere on here that temperature affects the spring constant. So would it hold true that at a stretched position the spring constant may vary - albeit very slightly? I'm doing my physics coursework and was wondering generally... might be an interesting observation to include don't you think. Feedback much appreciated, cheers.
