Mohr's circle and max stress

  1. Jul 4, 2016 #1
    1. The problem statement, all variables and given/known data
    a.)why the angle θ p is in clockwise direction? why shouldnt it be in anticlockwise direction?

    b.) I have labelled A,B ,C and D....Why the maximum normal stress is labelled at location A? while the min stress is labelled at location B?
    Can I label the min and max stress at other location? Say, max stress a t C , min stress at D? I dont understand why the the author label the max and min stress in that way...
