Since the shaft is rotating at a constant rate, y=0

To find Torque at B, M1 + M2 + M3 = 0

Q1. A VerticaL SHAFT BEARINGS AT ITS Ewoi Poiuts. THE SHAFT Is ROTATINA AT A is SUPPORTCO Bu FrietIoNess CONSTANT SPEEo. IF The MAXIMUM SHEAR STAESS IN THe BEAM IS 50MPA FIND THE MINIMUM OUA nETER OF THE SHAFT, - THe SHAFT Is SOLID THE PULLEYS ARE WEIGHTLESS - PIAMETERS FoR EACH PocLEy ARE GIveN. THERE's TonQue IN PULLEY B. 3 kN 1 kN 250 mm B -500 mm- 1 kN 1.25 kN 350 mm
