12. In problem 9, In the previous problem, is the flexural bending stress at C positive or negative? Is it in the x, y, or z direction?

What is the name of the fluid that lines the alveoli that keeps them from collapsing?

14. (3 bonus points to exam 2) 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?

What is medical term for fluid within the lungs?

8. (10 points) For the beam in problem 5, 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.
