16. A flywheel is suspended by resting the insido of the rim on a horizontal knife-edge Bo that the wheel can swing in a vertical plane. The flywheel has a nass of 350 kg. The knife-edge is parallel to and 360 mm from the axis of tho wheel. The time for making one small oscillation is 1-77 8 Assuming that the o.g. is in the axis of the wheel, find the radius of gyration about this axis. Also find the torque to increase the speed of the wheel at a uniform rato from 240 to 250 rev/min in s when the wheel isa rovolving about its axis. (U. Lond.) (Ans.: 387-2 mm; 73-25 N m)

Question
16. A flywheel is suspended by resting the inside of the rim on a horizontal
knife-edge so that the wheel can swing in a vertical plane. The flywheel has a
nass of 350 kg. The knife-edge is parallel to and 360 mm from the axis of thoe
wheel. The time for making one small OBcillation is 1-77 8 Assuming that the
o.g. is in the axis of the wheel, find the radius of gyration about this axis.
Also find the torque to increase the speed of the wheel at a uniform rato from
240 to 250 rev/min in s when the wheel is revolving about its axis. (U. Lond.)
(Ans.: 387-2 mm; 73-25 N m)
