Using the MOHR's Circle, determine

a$)$ the principal planes and stresses,

b$)$ the maximum shear planes and stresses,

c$)$ the stresses on an element oriented $60$ counterclockwise from the element shown.

Where:

X is the last digit of your student number

$Y$ is the second last digit of your student number

For example; if your student number is $201721001$ then

$5x=51$MPa;$3Y=30$MPa; and $Yx=01$MPa
