The derivation of Euler's equations of motion in using cylindrical vector components is beneficial in more intuitively describing the parameters relating to the balance of rotating machinery. Using the well established equation for Newton's equations in moment form and changing the position and angular velocity vectors to cylindrical vector components results in a set of equations defined in radius-theta space rather than X-Y space. This easily allows for the graphical representation of the intuitive design parameters effect on the resulting balance force that can be used to examine the robustness of a design. The sensitivity of these parameters and their influence on the dynamic balance of the machine can then be quantified and minimized by adjusting the parameters in the design. This gives a theoretical design advantage to machinery that requires high levels of precision such as a Computed Tomography (CT) scanner.
