9. For the beam in problem 6, what is the magnitude of the transverse shear stress in Segment 1 (0 < x < 1 m) at a location on the square cross section where the I = 8∙10-10 m4, Q = 1.25∙10-7 m5, the height and width of the square cross-section are 0.01 m.  Show all your work and calculations.

12. A point in a structure sees the following stresses σx = 1 ksi, σy = 2 ksi, σz = 3 ksi. What are the associated strains εx, εy, εz, knowing the modulus of elasticity is 30ksi and Poisson’s ratio is 0.3. If for a different point in the same structure with the same material, the strains are εx = 0.001, εy = 0.002, εz = 0, what are the σx, σy, σz stresses at that point?
