SUMMARY
The discussion focuses on deriving displacement functions 2-10 to 2-13 using third cubic polynomials and elementary beam theory. The user expresses confusion regarding the boundary conditions, specifically why the displacement at the start is defined as y(0) = θ₁ · L and why y(1) = 0 at the end. The parameters for the displacement functions are defined with respect to the normalized variable ξ, which ranges from 0 to 1. Clarification on these boundary conditions is essential for accurately deriving the displacement functions.
