Q 16. In a stressed body, an elementary cube of material is taken at a point with its faces perpendicular to X and Y- reference axes. Tensile stress equal to 15 kN/cm and 9 kN/cm are observed on these respective faces. They are also accompanied by shear stress equal to 4 kN/cm. The magnitudes of the principal stresses at the point are: Ops: A. O 17 kN/square cm tensile and 7 kN/square cm tensile B. 09.5 kN/square cm compressive and 6.5 kN/square cm compressive C. O 12 kN/square cm tensile and 3 kN/square cm compressive D. O 12 kN/square cm compressive and 3 kN/square cm tensile
