The document discusses various methods for analyzing beam deflection and deformation under loading, including: 1) Deriving the differential equation for the elastic curve of a beam and applying boundary conditions to determine the curve and maximum deflection. 2) Using the method of superposition to analyze beams subjected to multiple loadings by combining the effects of individual loads. 3) Applying moment-area theorems which relate the bending moment diagram to slope and deflection, allowing deflection calculations for beams with various support conditions.
