Isotropic Rayleigh - Ritz method

Calculation will be more accurate and brief. For example, we change the natural frequency and the beam cross section shapes, if asked to select with the same condemnation elastic dynamics of a Rayleigh Ritz method - Huang Qiang ZHAO Xiao-Yun Chen Shuxun 65 supporting the Cambodian situation of uniform section beam as a basis for the natural vibration mode function, good results can be obtained based wedge-shaped beam down the length z, width I, sharp edges free,MBT Shoes sale, blunt edge fixed, find the fundamental frequency of transverse vibration. Solution First,Nike trend shoes, write the cross-sectional area A () and flexural modulus (z) the expression: A () a 2b-type in rich abundance of a Ac A. A 26 × 1, is a wedge-shaped beam fixed end of the area;) = (word.
