The equation given is wrong. The true strain rate is equal to -v/l, l being the instantaneous length, not l_0, the original length. The equation given is equal to the engineering strain rate, with e in place of epsilon. I don't know how to edit those type of pages, so I won't do it myself, but can someone else change it?
