Statics problem, roller supports
Hello, I have a simple statics problem that's frustrating me.
The diagram shows a drum supported on free-spinning rollers, with an eccentric centre of gravity balanced by a torque applied to the drum with a universal joint. I am attempting to resolve the reactions at the roller supports. The rollers can only exert reactions radial to the drum.
Vertical components seem straightforward enough, by moments, but I'm baffled by the horizontal components. Where is the mystery force that will balance the horizontal components?
Thanks for any help.
