EXAMPLE 7.10. A circular ring of radius R and mass m made of a uniform wire of cross-sectional area A is rotated about a stationary veru axis passing through its centre and perpendicular to the plane of the ring. (a) If the breaking stress of the material of the ring is on, then determine the maximum angular speed om at which the ring may be rotated without failure. (b) If Young's modulus of the material of ring is Y, then determine the increment in the radius AR of the ring. max
