Q4 Consider a 2-DOF mechanical system with no external inputs. (35 marks) a) Derive its dynamic equation of motion from the following energy functions: (12 marks) $\mathcal{L} = \dot{q}^2 + \frac{3}{2}\dot{p}^2 - \frac{1}{2}(q - p)^2 - 5p^2$ Lagrangian function $\mathcal{R} = (\dot{q} - \dot{p})^2$ Rayleigh dissipation function b) Draw the schematic mechanical diagram of the system and find the values of its mass, damping, and spring components. (10 marks) c) Convert the system's equations of motion into a state-space representation by using a state vector defined as $x = [q, \dot{q}, p, \dot{p}]^T$ and an output $y = [2(p - q), \dot{q} + \dot{p}]^T$.

Consider the following set of equations: $\dot{x} = x^2 + y^2 - 1$ $\dot{y} = x^2 - y^2$ 1- Find the equilibrium points of this set of equations. 2- Linearize around these equilibrium points. Decide whether these equilibrium points are stable by using the Lyapunov linearization theorem separately for each equilibrium point. 3- Obtain the phase portrait of this set of equations using one of the free software available on the Internet. By looking at this phase portrait, show that your answer to the 2. question is correct.
