A hoisting system is used to lift the load of 70 kg with an acceleration of 2.0 m/s². The pulley has 380 mm diameter, radius of gyration 30 cm and mass 20 kg. A balancer of 40 kg is attached to the other string. Ignore the friction between rope and pulley. i. ii. iii. Draw the Free Body Diagram of hoisting system. Calculate the tension for each string. Find the torque to operate the system. After 5 seconds, the pulley has a stop. Determine necessary torque brake to stop movement of the load.
