1. The problem statement, all variables and given/known data A cylinder of radius R and mass m is lodged between cross pieces that make an angle θ with each other. The cross pieces of negligible mass are connected in point C, with lengths AC = BC = 2R and CD = CE = 3R. Determine the tension in the horizontal rope DE. You may assume smooth floor. 2. Relevant equations 3. The attempt at a solution My starting point was to calculate theta, which would be twice the inverse tangent of 1/3. I also know that the weight of the mass m will partner a reaction force that is spread evenly between the two points of contact with the ground. However I'm not too sure where to go from here and any help would be much appreciated!
