Random close pack crystal lattices have maximum densities equal to this upper limit. Random close packing does not have a precise geometric definition. It is defined statistically, and results are empirical. A container is randomly filled with objects, and then the container is shaken or tapped until the objects do not compact any further, at this point the packing state is RCP. The definition of packing fraction can be given as: "the volume taken by number of particles in a given space of volume". In other words, packing fraction defines the packing density. It has been shown that the filling fraction increases with
Rental agreement books from a library could be considered renting when there is a fee per book. However the term "lending" is more common. In addition to the above, a car rental agreement may include various restrictions on the way a renter can use a car, and the condition in which it must be returned.
