An engineering component has, at a certain point on its free surface, strains given by = 1.1e-3, = 2.0e-4, and = 5.0e-4. the young’s modulus is 200 gpa and possion’s ratio is 0.33. what tensile yield strength is needed for the material of this component if a safety factor of 3.0 against yielding is required? assume (a) the tresca yield criterion, and (b) the von mises yield criterion.
