3. The state of stress at a point in a continuum body is given by X 1.5 0 1.0 0 00 [a] 1.5 0 MPa where X is a non-zero value but has not been determined. If the body is made up of a brittle material that fractures along the plane of maximum principal stress and the critical tensile stress at which fracture occurs is 5 MPa, (a) what is the maximum value of X that the body can sustain without fracture? (b) if X were to reach the critical value, what would be the orientation of the fracture plane? Show the stress state on a properly oriented element.
