A smooth-walled 100 mm edge steel bucket is filled with rubber to form a rubber bucket embedded within the steel bucket. If the rubber hub is compressed by a 100 kN force, determine: a) The normal contact stress between the rubber and the inner walls of the steel. b) The change in volume experienced by the rubber bucket. Consider the following: - The steel bucket is rigid. - There is no friction between the smooth walls of the steel bucket and the rubber (shear stress equal to zero between steel and rubber). - Rubber properties: E = 4 MPa and v = 0.45.
