Extracted text: The stresses at a point on the surface of a generator shaft are o =-50 MPa, o, = 30 MPa and Try shown in Figure Q3. (Consider only the in-plane stresses. Note: the radius of the = -40 MPa as circle is given by R = ) + ()). Construct the Mohr's circle showing the centre of the circle as well as points A and B. (a) (b) Determine the principal stresses. (c) Show the principal stresses on a sketch of a properly oriented element. (d) Determine the maximum shear stresses. (e) Show the maximum shear stresses on a sketch of a properly oriented element.
