What would you do knowing that after your goneThats itNo more people.?
If your knee is still hurting you then you can ask for workers comp if that employee pays into the system. You can try to sue if you are still injured. If you are not still injured then you have missed out because there is a statute of limitations involved in the time you were injured and the time you file your claim. An employer has the right to hire or fire whom they please and sometimes there is little you can do about it.
Elastic bands likely follow Hooke's law approximately only for a limited range. Glass and steel are far more 'elastic.' If you drop a 'ball' of a given substance and it returns to the exact same elevation, it is perfectly elastic (giving back all its stored energy due to the fall). Putty is far less elastic than rubber. Rubber (natural or synthetic) is composed of polymers (large strings of molecules that use space inefficiently). When you stretch an elastic band it pulls all the molecules into nearly a straight line (eliminating 'wasted' space). After that the molecules resist further stretching. Rubber is also a plastic (can be molded) and possesses an 'elastic' memory. If you roll out a thin sheet of plastic from a ball (with a rolling pin?) then heat it, plastic memory tends to roll it back up into a ball but never gets there. It only curls a little. Plastic memory should try to return an elastic band to its original length but likely never gets there. Elastic bands are often made by dipping a long dowel (etc.) into liquid polymer and curing it (to make it semi-solid). The diameter of the dowel and the width of circular cuts determines the shape (oval?), length and width of the band and the amount of polymer allowed to collect determines its thickness. As such there is nil tension in an original elastic band and little available force to return it exactly to its original dimensions.
