Figure below the hoist machine has a mass of 800 kg and the counterweight C has a mass of 150 kg. At a given instant, the hoist machine motion upward with velocity of 2 m/s an acceleration of 1.5 m/s 2 . The tension in cable on the motor can withstand a maximum tension of 3000 N, is the system safe? If no, redesign the system so that it is safe. What will the minimum power of the motor be if the efficiency is restricted to 80%? Justify your answer with calculation.

Figure below the hoist machine has a mass of 800 kg and the counterweight
C has a mass of 150 kg. At a given instant, the hoist machine motion upward with
velocity of 2 m/s an acceleration of 1.5 m/s 2 . The tension in cable on the motor can
withstand a maximum tension of 3000 N, is the system safe? If no, redesign the system so that it is safe. What will the minimum power of the motor be if the
efficiency is restricted to 80%? Justify your answer with calculation.
