Plot a Mohr’s circle for the following stresseson a square soil element:
σx = 100kPa
σy = 200kPa
τxy = 20 kPa (forceis counterclockwise on the top horizontal surface of theelement)
Determine the following (either from the circle or from equations):
a. Principalstresses
b. Angle of the planeson which the principal stresses act
c. Shear and normal stresses on aplane that is 37 degrees from horizontal
