I need to figure out the torque required to rotate a drum. The drum is being rotated on its perpendicular axis. I am designing a drum dumper so the drum starts upright and is rotated 135 degrees to dump its contents into a hopper in the floor. I want it to take about 5 seconds to do the rotation at about 30rpm. The pivot point is about 7.5" up vertically off center. I thought I was using the right equations but my answer is not logical.
