In the present paper, the different techniques used for the determination of changes of surface stress of solid electrodes, as well as the kind and quality of information that can be achieved using these methods are discussed. The most important methods are briefly reviewed and advantages/drawbacks highlighted. Special attention is paid to issues related to the use of the “bending beam” (“bendi...

The equation of motion of a rotating cantilever beam in a vertical plane is derived based on Hamilton’s principle and assumed mode method. The effect of gravity on the stability of the beam with constant angular velocity is then examined using Bolotin’s method. The regions of ins~bi~ity are determined by converting the resulting equations of boundary frequencies to the standard form of a genera...
