Compute the torque TB and Tc due to tensile forces in the belts at point B and C, respectively. 6. Draw the torque diagram to show the level of torque in all segments of the shaft. 7. Compute the nominal torsional stress and on the outer surface of the shaft for cross sections passing through points B and C due to the torque TB and Tc. 8. What is the value of the shear stress at the center of the cross section passing through point B and that passing through point C? 9. Assuming that the shaft is made of steel, compute the angle of twist of the cross section passing through B with respect to that passing through point C. 10. Determine the stress concentration factor K, in torsion, for a sled-runner keyseat. 11. Using the stress concentration factor K just determined, calculate the shear stresses to and TC on the outer surface of the shaft for cross sections passing through points B and C, respectively.
