- Use The Rayleigh Ritz Method To Find Good Approximations For The First 3 Natural Frequencies And Modeshapes Of A Steel B 1 (17.32 KiB) Viewed 40 times
Use the Rayleigh-Ritz method to find good approximations for the first 3 natural frequencies and modeshapes of a steel beam with length 1 = 10 m, cross-sectional area A = 44 cm² and 1 = 1.0(107) mm". The beam is pinned at the left end and supported at the right end by a spring with stiffness k=10 kN/m. Use trial functions 4:(x) = sin({inx/1).
