There is a recessed beam at both ends. The cant at point A is 0.7 m. The cant at points B and C is 0.5 m. The beam has a constant width of 0.3 m. Solve the structure using the Rayleigh-Ritz method. Use a cubic equation for the displacement field of AB and a quadratic equation for the displacement field of BC. Find the displacement and rotation at point B and the bending moment at points A, B, and C.
