The countershaft is powered via two V-belt pulleys with the shown tensions and runs at a constant speed. Pulley A relieves power from the motor and transmits it through the shaft to Pulley B. Assume the belt tension on the loose side of Pulley B is 20% of that on the tight side. (a) Calculate the tensions in the V-belt at Pulley B. (b) Generate the V-M Diagram for the setup. 300 dia. (c) Identify the critical element. (d) At the critical element, calculate the max bending 10 dia. stress and torsional shear stress. (d) At the critical element, calculate the principal stresses and maximum shear stress. ag 200 250 N 400 100 N T₁ 60° 100 250 dia. "Lengths are in mm.
