1. The problem statement, all variables and given/known data Hi, I am doing some things with Mohr's circle. I am trying to find the direction of max strain but I am a bit confused. How can I do this? 2. Relevant equations 3. The attempt at a solution I always assumed that the max strain occurs at 90O from the normal axis or 45O in real life. But I used a online calculator and got an angle of about 40O so that means that it isn't always at 45 like I thought. Can anyone lend a hand? Thanks!
