An electric motor drives a punching press. A flywheel fitted to the press has a radius of gyration \(0.4 \mathrm{~m}\) and runs at \(240 \mathrm{rpm}\). The press is capable of punching 600 holes per hour with each punching operation taking 1.5 seconds and requiring \(10000 \mathrm{~N}-\mathrm{m}\) of work. Determine the rating of the machine in \(\mathrm{kW}\) and the mass of the flywheel if the speed of the flywheel does not drop below \(220 \mathrm{rpm}\).
