Pulses of fluidization are used to prepare static sedimented states with well-defined particle volume fractions Phi in the range 0.57–0.63. The resistance to shear is determined by slowly inserting a rod into the column of beads. Force measurements and bed height measurements both indicate that the transition occurs at Phi = 0.60 for a range of speeds of the rod.
