A circular ring of radius `R` and mass `m` made of a uniform wire of cross sectional area `A` is rotated about a stationary vertical axis passing throgh its centre and perpendicular to the plane of the ring. If the breaking stress of the material of the ring is `sigma_(b)`, then determine the maximum angular speed `omega_("max")` at which the ring may be rotated without failure.
