A beam AB of span 'l' simply supported at the ends and carrying a concentrated load ' $W$ ' at the centre ' $C$ '. Determine the deflection at the mid span by using Rayleigh-Ritz method and compare with exact solution. ( $\mathbf{4} \boldsymbol{\times} \mathbf{2 0} \boldsymbol{=} \mathbf{8 0}$ Marks)
Explanation
The Rayleigh-Ritz method is a semi-analytical technique used to solve for the deflection of a beam. In this problem, we used the method to determine the deflection at the mid-span of a simply supported beam carrying a concentrated load. The result obtained using the Rayleigh-Ritz method matches the exact solution.
