The 4.8 m I-beam has a mass of 900 kg and is held in the horizontal position by the pin at O and by the vertical cable which passes around the pulley at A and around the drum of the 200 kg motorized winch at B, as shown in Figure 8. If the winch motor has an output starting torque of 800 N.m, calculate the reaction forces at the pin O given the moment of inertia of the whole system including the winch, lo 7272 kg.m?. Treat the beam as a slender bar and the winch unit as a mass concentrated at the centre of the pulley.
