5. (8 Points) Calculating maximal shear stresses. Given a body under the following state of triaxial stress represented in x, y, z-coordinates 100 0 0 = 0 40 0 MPa 0 0 60 (a) What is the magnitude of the maximum shear stress? (b) What is the normal vector to the plane on which the shear stress is greatest? (c) Draw the projections onto the x- y plane (i.e. a 2D stress element with x and y components) of stress elements corresponding to the principle normal stresses and the state of maximal shear stress. 5.
