Hey. I've been having some trouble getting through Mohr's circle. The googles that I've found haven't been too useful. I've seen several questions of the same calibre and what I generally need is how to derive the magnitude/direction of the principal strains as well as the principle stresses when given a set up like a rosette gage with 3 strains at 60degrees, with for example 100 epsilon - 200 epsilon- 300 epsilon on each axis. If you can show me an example solution or the general procedure, preferrably illustrated, I'd be that much wiser. Thanks in advance.
