Bending stress in a ring
Bending stress in a ring
(OP)
I can't find any formulas for my problem. I work on a purification dryer who's fit in 2 large rings. Each ring roles on 2 rollers each make a angle of 28° with the vertical axes. The rings have an internal diameter of 2568mm and an outside diameter of 2848mm. It has an rectangular section 260mm wide and a height of 140mm. There is product in one ring with a force of 125kN 136mm next to the center of the ring and a force of 480kN in the center of the ring. These 2 are vertical forces. The ring is supported with 2 reaction forces in the rollers under need it. These have the angle of 28° with the vertical axes. Anyone who can help me? Thanks.

This is a picture of the dryer. The problem with Roark's formulas for rings is that the force C is not there. The force is the weight of the dryer and this does not just push in the middle the ring downstairs but the force is also present everywhere in the ring not just on the upper point.

N = axial force (see the legend here attached for the units). See also the note for + or -
"m" and/or "n" are the coeff listed according to the different angles (there is a mistake in the list : they are listed as M and N, but they should be deemed as m and n)
