These nuances are apparent even in simplified two-dimensional models because of the depth of the relationship between a container's geometry and achieving balance. The purpose of such analysis is threefold: first, when considering a rectangular container, to determine the relationship between the angle at which it balances and the amount of fluid in the container; second, to consider a massless analogue to a standard twelve-ounce aluminum can which balances at a fixed angle and observe the interplay between the various parameters of that container's geometry and balance; and finally, to revisit the aluminum can model, this time considering its mass relative to the fluid's, and recover the familiar behavior observed when balancing real-world beverages in aluminum cans.
