Nettet1. mar. 2013 · Dimentberg [1] performed an in-depth study of spinning beams using the Euler–Bernoulli beam theory. Bauer [13] investigated spinning dynamics of Euler–Bernoulli beams with ten different sets of boundary conditions, and compared the natural frequencies of a spinning beam with those of a non-spinning one.

Nettet1. feb. 2024 · It is observed that the axially moving beam with dimensionless flexural rigidity of 0.1, 0.3 and 0.5 have dominant vibration frequencies at 110, 190 and 250 Hz, respectively. Influence of the flexural rigidity of the beam on its motion periodicity is observerd in the phase portriat Poincaré map demonstrated in the Fig. 8, Fig. 9. In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams. fortnite recommended specs

This is because the effect of transverse shear strains, neglected in the classical theory, becomes significant in deep beams and thick plates. Nettet15. des. 2024 · STAUNTON, Va.
