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 a mobility of at least said portion of said object under said plurality of increments of weight loads.
