145 A closed chain A of mass m 0 36 kg is attached to a vertical rotating shaft by means of a thread Fig 1 37 and rotates with a constant angular velocity 35 rads The thread forms an angle 0 45 with the vertical Find the distance between the chain s centre of gravity and the rotation axis and the tension of the thread 146 A round cone A of mass m 3 2 kg and half angle a 10 rolls uniformly and without slipping along a round conical surface B so that its apex O remains stationary Fig 1 38 The centre of gravity of the cone A is at the same level as the point O and at a distance I 17 cm from it The cone s axis moves with angular velocity on Find boog oooooo 2a m Fig 1 36 Fig 1 38
