Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 16 MPa in size. (a) Determine the stresses Ox, Oy, and the magnitude of Txy and show them on a stress element. (b) Determine the stresses on, 0t, and the magnitude of Tnt 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 (i.e., either clockwise or counterclockwise). y σ n Answer: (a) Ox= 30 MPa Oy = -90 MPa Txy= 90 MPa (b) On- 80 MPa Ot- - 120 MPa Tnt - 30 MPa
