thanks dicer and jraef for valued time..the cylinder is placed on a rotating platform,which is fitted with a smooth bearing.so i think coefficient of friction and the power to rotate the platform can be considered as negligible.only the job mass matters...thanks..
Dear friends..
i was trying to figure out the required torque(NM)and power of motor(HP)to rotate a cylinder, placed vertically on a turn table.
cylider OD=2 meter , ID=1.5 meter. weight of the cylinder is 7500 kg. required constant RPM = 0.1 . any help please..
