Consider a point in a structural member that is subjected to plane stress. Normal and shear stresses acting on horizontal and vertical planes at the point are shown. If o = 39 MPa in the direction shown, identify the stress element that best depicts the principal stress state at the point. 45 MPa 35 MPa 50°
