Question 2. An elevator with a loaded mass of 1000 kg is to be lifted at uniform speed of 1.5 m/s. The elevator couples to a drum of inertia 10 kgm? and efficiency of 85%. The drum applies torque of 10 Nm, with the drum diameter having a gearing ratio of 1:10 and efficiency of 90%. A motor ultimately drives the drum at constant speed of 1450 r/min. If the motor has inertia of 0.2 kgm?, (a) what power should the motor develop to drive the system? [30 marks] (b) what inertia does the motor experience as it drives the system? [10 marks]
