SUMMARY
The discussion centers on the calculation of normal and shear stresses on a plane inclined at 30 degrees anticlockwise from plane AD using Mohr's Circle. The original poster (OP) applies the formula for maximum and minimum stresses, yielding results of 32.3 MPa and -22.3 MPa, which differ from the expected answers of 12.5 MPa and -2.3 MPa. The OP questions the validity of their calculations and whether their understanding of the concepts is flawed, particularly regarding the angle of principal stresses derived from the equations.
