| Sep 6, 2017 at 21:37 | comment | added | Todd Wilcox | It might help to also remember that all of the formulae we use in physics are really models that approximate the actual world closely enough that we can use the results the models give us to do things, like build working machines and accomplish tasks with those machines. The models/formulae shouldn't be taken to indicate the exact, actual behavior of anything. | |
| Sep 6, 2017 at 16:40 | comment | added | JMac | @PaulSinclair Good point. You could do this with any appropriately designed system as long as it behaves like a "spring". I just find coil springs are the easiest example, where everyone has seen them and understands approximately what they do. | |
| Sep 6, 2017 at 16:30 | comment | added | Paul Sinclair | Your post is apropos to coil springs. There are other forms of springs that do bend, not twist. In fact, a bar anchored on one end is a very common form of spring. Of course, for OP's purposes, looking only at coil springs is acceptable (and maybe preferable). | |
