I would like to ask you some question, which I am currently working on. We have a column and around this column is attached metal ring (locked with bolts of course), which are going to carry lamps(attached to the cylinder, look the atached file). I would like to ask you if there is a way to calculte the friction force which this ring exerts on the column, if it stars to fall down and mostly is there a way to calculate to the total force or stress acting on the column if the bolts ae pretension and the locked for the ring around the column. WHat is gonna be the total force? Because if you imagine the bolts are maximum tensioned and the ring somehow "squeez" and shrink, then this will cause stress on the column?
Didn't get the answer.
