Question
In the figure, shaft AB transmits power to shaft CD through a set of bevel gears contacting at point E. The contact
force at E on the gear of shaft CD is determined to be (FE)CD = –92.8i – 362.8j + 808.0k lbf. For shaft AB: (a) draw a
free-body diagram and determine the reactions at C and D assuming simple supports (assume also that bearing A
carries the thrust load), (b) draw the shear-force and bending-moment diagrams, (c) for the critical stress element,
determine the torsional shear stress, the bending stress, and the axial stress, and (d) for the critical stress element,
determine the principal stresses and the maximum shear stress.
