A hollow disc (Plane stress) of inner radius a and outer radius b, modulus of Elasticity E Poisson’s ratio v, and density p, is co-centrically placed in an otherwise rigid housing to which a frictionless bearing is attached o its inner surface as shown in the figure. An initial clearance & exists between the outer surface of the elastically leforming rotating disc and the inner lining of the frictionless bearing. a) Determine the angular velocity o at which the disc comes in contact with the frictionless bearing. b) If the angular velocity is further increased to @1> @, determine the pressure that develops between the frinctionless bearing and the outer surface of the rotating disc. Rigid -Frictionless bearing a E, v
