1. A method for determining a mobility of an object, comprising: a) measuring at least a portion of a shape of said object under an initial increment of a weight load of a plurality of increments of a total weight load using a device; b) measuring said at least said portion of said shape of said object under a next increment of a total weight load of said a plurality of increments of a weight load using the device; c) repeating step b) until a total weight load is achieved; and d) comparing said measurements from the device under said plurality of incremental weight loads, thereby determining said mobility of at least said portion of said object under said plurality of increments of weight loads.
