Extracted text: 2. Two planes AB and BC which are at right angles are acted upon by tensile stress of 150 N/mm and a compressive stress of 35 N/mm respectively and also by shear stress 75 N/mm. Determine: a) the magnitude and direction of the principal stresses. b) the magnitude and direction of the max-in plane shear stress. c) the state of stress at the point on another element oriented 30° clockwise from the position shown by using both the equations and Mohr's Circle 35 N/mm 75 N/m 150 N/mm
