WebDuffing's equation is the second-order nonlinear equation (5.18) where k, Γ, and ω are positive constants. Depending upon the values of the parameters, solutions to Duffing's equation can exhibit very interesting behavior. 1. Graph the solution to Duffing's equation using twelve equally spaced values of Γ between 0 and 0.8 if , , , and for . WebDuffing's equation is a model for a dynamic system that includes a damping term and a nonlinear stiffness term. It most notably describes dynamics of electrical systems, but it has a simple analog as a nonlinear vibrations problem. Derive the non-homogeneous Duffings equation below using Hamilton's Principle.
