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 ...
Nursery culture of sandfish Holothuria scabra in sea-based floating hapa nets: Effects of initial stocking density, size grading and net replacement frequency Sea-based culture of early juvenile sandfish Holothuria scabra up to fingerling size (>2 g) using floating hapa nets has been confirmed as...

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: ...
Natural frequencySteel beamPredictionAxial loadForce predictionQuick monitoring of the axial force of hangers of a suspension or a cable-stayed bridge are of significant importance since large vehicle loads may have affected, if not changed, the axial forces along the life cycle of the bridges. ...
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 ...
To verify Equation (22), the first five natural frequencies were calculated for three well known cases: Case 1: Clamped-free [14]: 𝑎𝐿=𝑚attached𝑚beam=0aL=mattachedmbeam=0 Case 2: Clamped-free with mass at free end [7]: 𝑎𝐿=0aL=0 Case 3: Clamped-pinned-free [6]: ...
