The state of stress at a given point in a loaded component is given by sx, sy and Txy and the principal stresses at the point are s1 and s2. If the new axes at the point are changed to x1 and y1 such that state of stress w.r.t. the new axes are sx, sy And Tx'y'.

(i) Show that sx + sy + sy  - s1 + s2.                                                                                              

(ii) Sketch the Mohr's stress circle for pure shear stress state and hydrostatic state of stress. 

(iii) A cast iron bar of 30 mm diameter and 1 m length is subjected to equal & opposite torque T applied at its ends. If tensile strength of cast iron is 80 MPa, what is the maximum value of torque T? show that plane of failure for the applied sends of torque T.
