Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 5 MPa in size. (a) Determine the stresses O, Oy, and the magnitude of Tand show them on a stress element. (b) Determine the stresses O Op and the magnitude of Tt and show them on a stress element that is properly rotated with respect to the x-y element. The sketch must include the magnitude of the angle between the x and n axes and an indication of the rotation direction (l.e, either clockwise or counterclockwise).
