For a cantilever beam with elastic modulus E loaded by a couple M at the free end, the following stress field is proposed: σ.-Dy, σ,-σ.-TE,-T.-T, CD is a constant) a. Show that this stress field satisfies the three equations of equilibrium and the six compatibility equations. b. Show that the top, bottom, front, and back surfaces are traction free for this set of stresses. c. Show that the resultant normal and shear force are zero on the free end. d. Evaluate the constant D such that the resultant couple on the free end equls the given couple M, that is, M-o,ty)dy. e. Evaluate the displacements of the beam if u-w-0 and Uniform cross section
