What is Rayleigh-Ritz Method for Beam Analysis about?

The Rayleigh-Ritz method and finite element method are introduced for discretizing distributed-mass systems with infinite degrees of freedom into systems with a finite number of degrees of freedom. The Rayleigh-Ritz method uses trial functions to express the system deflections, resulting in a matrix eigenvalue problem that approximates the natural frequencies and modes. The finite element method similarly replaces the partial differential equation with ordinary differential equations, allowing numerical sol
