The name is a common misnomer used to describe the method that is more appropriately termed the Ritz method or the Galerkin method. This method was invented by Walther Ritz in 1909, but it bears some similarity to the Rayleigh quotient and so the misnomer persists.

Which among the following method is used to find a functional relationship with respect to a parameter? Explanation: Rayleigh’s method is a basic method for finding the functional relationship. The functional relationship is found with respect to a physical parameter. It is illustrated using the MLT system.

The main limitation of the Rayleigh’s method is that it has exponential relationship between the variables. It makes it more complex for solving. Since, more variables with exponents will lead to a confusion in the solving process. Rayleigh method Becomes laborious if variables are more than fundamental dimensions.

Rayleigh–Ritz or Ritz Method The Rayleigh–Ritz method enables one to reduce an infinite number of degrees-of-freedom of a system into a finite number, which makes analysis possible and easier. The method relies on the approximation of the possible deformation shapes of the system, following the basic idea beyond Rayleigh’s principle.

RAYLEIGH’S METHOD. Introduction. Dynamic systems can be characterized in terms of one or more natural frequencies. The. natural frequency is the frequency at which the system would vibrate if it were given an. initial disturbance and then allowed to vibrate freely.

Following the Ritz method the family of curves over which the values of the functional are calculated is obtained by a linear combination of functions: Here, αi, are constants and ςi are functions that satisfy certain end conditions. Hence, the shape of the function ϕ is determined by ςi; while its values are determined by the coefficients αi.
