Theories of Failures Q.24 A point in a solid shaft under action of bending moment and twisting moment develops principal stresses as σ₁ = 80 01 o. N/mm² (tensile) and o₂ = 30 N/mm² (compressive). Shaft material is ductile with yield strength of 210 MPa, Poisson's ratio μ = 0.25. Determine the factor of safety according to maximum principal strain theory.
