Given the open-loop transfer function of a unity feedback system: $$G(s) = \frac{1}{4s^2(s^2+2)}$$ Tasks: (a) Find the closed-loop characteristic equation (b) Use MATLAB to build the Routh table of the closed-loop system. (c) Identify the location of closed-loop poles (RHP, LHP, or jω-axis). (d) Determine if the system is stable, marginally stable, or unstable.

Q1. Starting from $\mathbf{n} = \mathbf{W}\mathbf{n} + \mathbf{D}\mathbf{n} - (\mathbf{D}\mathbf{n} \cdot \mathbf{n})\mathbf{n}$ where, $\mathbf{n}$ is the unit vector in the direction of the deformed material filament originally in the direction N. Show that: a) Show that the rate of shear between two filaments is given by: $ -\sin(\theta)\dot{\theta} = 2\mathbf{D}\mathbf{n}_1 \cdot \mathbf{n}_2 + (\mathbf{n}_1 \cdot \mathbf{n}_2)(-\mathbf{D}\mathbf{n}_1 \cdot \mathbf{n}_1 - \mathbf{D}\mathbf{n}_1 \cdot \mathbf{n}_1) $ (1) b) Hence conclude that the off-diagonal components of D capture the rate of shear. c) Also, from this show that filaments along the eigenvector directions of D rotate rigidly.

Q1. (20P) Set up the mathematical formulation of the following heat conduction problems. Formulation includes the simplified differential heat equation along with boundary and initial conditions. Do not solve the problems. a) A slab in $0 \le x \le L$ is initially at a temperature g(x). For times t > 0, the boundary at x = 0 is kept insulated, and the boundary at x = L dissipates heat by convection into a medium at $T_\infty$. temperature b) A semi-infinite region $0 \le x \le \infty$ initially at a temperature f(x). For time t > 0, heat is generated in the medium at a constant uniform rate of $q_0$ (W/m³), while the boundary at x = 0 is kept at zero temperature. c) A hollow cylinder $a \le r \le b$ is initially at a temperature f(r). For times t > 0, heat is generated within the medium at a rate of $q_0$ (W/m³), while both the inner boundary at r = a and outer boundary r = b dissipate heat by convection into medium at fluid temperature $T_\infty$.
