Consider the assembly shown below. The diameter of solid shaft ABD is 12 mm. (Keep all units in SI) a. Considering the effects of axial force, transverse shear, torsion and bending moments (about two different axes), which cross section of the shaft (from A to D) do you think will experience the most stress? Justify your answer, and make sure you get this right before proceeding with the problem. b. Using a free body diagram, determine the axial force, shear force, torsion, and bending moments at that cross section. c. Now, based on your knowledge of the distributions of stress due to these internal forces and couples, locate the critical point within this cross section. Note, it may be reasonable to neglect the stresses from one of your internal forces, but make sure you justify your reasoning. d. Now identify a stress element at that point and draw the stresses acting on it. e. Now draw Mohr's circle, determine the principal stresses and maximum in plane shear stress, and draw those elements. f. Determine the third principal stress and the absolute maximum shear stress. 55 12 dia B 300 N 40 200 N E 50 60 Consider the assembly shown below. The diameter of solid shaft ABD is 12 mm.
