If the mass of the cord is included in the analysis, the system is continuous and there will be infinite number of natural frequencies. If the cord is replaced with a uniform Euler-Bernoulli beam pinned to the hub and the bob is a particle, the mode shape differential equation is fourth ...

New closed-form solutions for the natural frequency of a clamped–guided beam are derived in this investigation. By postulating the mode shape of the clamped–guided beam, whose material density and stiffness are taken as polynomial functions, one is able to calculate the closed-form solution ...
In this study, new closed-form solutions for the natural frequency are derived for a beam guided at one end and pinned at the other end. As in Elishakoff and Guede (cf. Elishakoff I, Guede Z. Family of analytical polynomial solutions for simply supported inhomogeneous beams, part 1: ...
