Consider a point in a structural member that is subjected to plane stress. Normal and shear stress magnitudes acting on horizontal and vertical planes at the point are Sx = 195 MPa, Sy = 130 MPa, and Sxy = 45 MPa. Assume. Construct Mohrs circle for this state of stress on paper and use the results to answer the questions in the subsequent parts of this GO exercise. For this Mohrs circle, point x, which represents the state of stress on the x face of the stress element, should appear:
