The thrust of propeller shaft is absorbed by 5 collars. The rubbing surfaces of these collars have outer diameter 280 mm and inner diameter 178 mm. If the shaft runs at 115 rpm., the bearing pressure amounts to 0.38 N/mm. The coefficient of friction may be taken as 0.055. Assuming that the pressure is uniformly distributed, determine the power absorbed by the collars.
