The countershaft and pulley system operate at a constant velocity. Pulley A relieves power from a motor and transmits it through the countershaft to Pulley B. Assume the loose side of the belt on Pulley B experiences 15% of the tension on the tight side. (a) Calculate the tensions in the V-belt at Pulley B. (b) Generate the V-M Diagram for the setup. (c) At the critical element, calculate the max bending stress and torsional shear stress. (d) Determine the Principle Stresses and Maximum Shear Stress (e) Using that same shear stress, determine the size of a square shaft that would be equivalent to the existing round shaft in resisting failure. 10 in 500 lbf 75 lbf 8-in dia. 18 in 14-in dia. 12 in T₂ B 10-in dia.
