3. At the point labeled A in the bracket below, the stresses are og = 4.8 ksi, o, = -1.2 ksi and Ty = -4.0 ksi. The angle 0 = 20°. Use the plane stress transformation equations to determine og , Jy, and Tyryı. Show these stresses on a properly oriented element. 1.2 ksi 4.8 ksi 4 ksi 4. At a certain point on the surface of a machine part, Og = -7 MPa and oy = 3 MPa. The maximum in-plane shear stress at this point is Tmax = 10 MPa. Determine the magnitude, T, of the shear stress at this point on the machine part and determine the principal stresses at this point.
