8. In the figure below 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 on shaft CD is determined to be \(F_{E}^{CD} = -104.1i - 310.6j + 900k\) lb. For
shaft CD:
a. Determine the support reactions at the bearing assuming bearing C carries the thrust load.
b. Calculate the torque on shaft CD.
c. Draw V&M diagrams and locate the maximum bending moment on the shaft.
d. Find the torsion, bending and axial stresses at the critical point on shaft CE.
e. Find the principal and maximum shear stresses for the critical point on shaft CD.
[Answers: Torque = 3492 lb-in, Dz = -342.1 lb, Dx = -156.95 lb, Cx = 261.05 lb, Cy = 310.6 lb, Cz = -557.9 lb,
maximum bending moment = 1435 lb-in, normal stress = -10.44 ksi, shear = 12.33 ksi, max shear = 13.39
