Q6) A shearing machine has a flywheel of mass 1220 kg with a 0.58 m radius of gyration. During a 150 mm cutting stroke the speed falls from 200 to 180 rpm. The work done during cutting is equivalent to kinetic energy of the flywheel.

Calculate EACH of the following

(a) Torque required to attain a speed of 200 rpm in 60 seconds from rest; (6)

(b) Average cutting force of the shearing machine; (8)

(c) Angular impulse transmitted to the flywheel during cutting. (2)
