- The layout of transmission shaft carrying two pulleys B and C and supported on bearings A and D is shown in Figure below. Power is supplied to the shaft by means of a vertical belt on pulley B, that is then transmitted to pulley C carrying a horizontal belt. The maximum tension in belt on pulley B is 2.5 kN.
