can appreciate that fig3 is presented for illustrative purposes only and that a variety of washing machine configurations and other rotating devices not illustrated herein may be utilized to implement varying embodiments of the present invention washing machine 81 is thus described herein for illustrative purposes only and is not considered a limiting feature of the present invention 0040 fig5 illustrates a three dimensional schematic representation of the forces and critical lengths along the axis of rotation which has been extended along the length of the shaft and through the length of the drum force sensors may be mounted to measure the force transmitted between housing mount 64 and bearing housing 58 as illustrated in fig2 the basic concept of dynamic balancing stipulates that vector forces at the front and back cups may represent an out of balance condition referring to fig5 the system may be provided with a mechanism for sensing a first force f backsensor at a first location 100 of the axis of rotation and a second mechanism for measuring a second force f frontsensor at a second location 102 of the axis of rotation it should be understood that both the first and second forces shown in fig5 are likely to be determined from a plurality of force sensors arranged so that the resultant force vectors along multiple axes of the system can be determined at each of the first and second locations 100 and 102 of the axis of rotation if a washing machine or similar apparatus with a rotating member is rigidly attached to a stationary object such as a concrete floor a mere force and moment analysis based.
