Problem 7.2-18 The surface of an airplane wing is subjected to plane stress with normal stresses o, and o, and shear stress Ty, as shown in the figure. At a counterclockwise angle 0 = 32 from the x axis, the normal stress is 37 MPa tension, and at an angle 6 = 48, it is 12 MPa compression. If the stress o, equals 110 MPa tension, what are the stresses o, and T,? Try o, = 110 MPa
