Question

Figure 1 shows a motor (A) rotating a fly-wheel (B) which in turn lifts a heavy mass 0 kg. The power delivered to the motor changes over time to maintain a acceleration. The mass, initially at rest, is lifted a total distance of 5 metres in s. The fly-wheel has a moment of inertia of 1 28 kgm2 about its axis, with lus router-0.9m, and inner radius ?nner-0.5m. The radius of the motor nstant the outer radi is TA-0.05m. Given that power may defined as Power = torque × angular velocity Determine the maximum power required from the motor. outer inner mM Figure 1
