Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 12 MPa in size. (a) Determine the stresses o, Oy, and the magnitude of Ty and show them on a stress element. (b) Determine the stresses an, O, 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 (i.e., either clockwise or counterclockwise). Answer: MPa (a) Ox= MPa Oy = MPa Txy= (b) ơn= MPa MPa Tnt= MPa

Mohr’s circle is shown for a point in a physical object that is subjected to plane stress.  Each grid square is 8 MPa in size.(a) Determine the stresses σx, σy, and the magnitude of τxy and show them on a stress element.(b) Determine the stresses σn, σt, and the magnitude of τnt 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).

Mohr’s circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 600 psi in size. (a) Determine the stresses σx, σy, and the magnitude of τxy and show them on a stress element. (b) Determine the principal stresses and the magnitude of the maximum in-plane shear stress acting at the point and show these stresses on an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16).
