Torque required to turn a drum/barrel - Physics Stack …

Theoretically, zero torque is required to start the barrel turning as long as it starts out in equilibrium. To keep it turning at a constant speed, the required torque varies periodically with a time-average of zero. This assumes that there is no friction in the barrel and that the dirt doesn't roll around inside.

How to Convert Torque to Force | Sciencing

Torque is the application of force through the use of a lever rotated around an axis. A good example of torque in action is a wrench. The head of the wrench grabs a bolt and applies pressure to it. If you kept applying pressure, the wrench would eventually rotate around the bolt.
