Indicate principal stresses and the maximum shear stress for each Mohr's circle. g) At B, determine the overall maximum shear stress (max Maximum of (102|1031) (01-03) 2 and maximum normal stress such that h) For a Brittle Material, determine the factor of safety at point B using the Rankine Criterion (a.k.a., maximum normal stress criterion) with S-350 MPa (only tensile test results are available). Is this design safe using this material? Explain. i) For a Ductile Material, determine the factor of safety at point B using the Tresca Criterion (a.k.a., maximum shear stress criterion) with S,-315 MPa and S-375 MPa. Is this design safe using this material? Explain.
