Hey. I have a question. What is the packing fraction of a container full of randomly jammed cylinders? Also, does the packing fraction depend on the ratio of the radius to height of the cylinder? There is some contest of finding certain amount of cylindrical objects inside a container (I cant weight it) and I know that for certain shapes, you can use the packing fraction to estimate (Spheres have a random packing of .64). I already planned the way I am doing this (finding volume, size of discs, etc) and this would be perfect with the packing fraction of cylinders. Youll help me loads.
