Consider the mass-spring-damper system shown in Figure [3A.1] where k = 10 [lbf/in], m = 1 [lbf.s^2/in], and b = 2 [lbf s/in]. 2. Draw a linear graph and normal tree representing this system. 3. Create a block diagram in Simulink that will simulate the response of this system to the input vs(t) = 5 sin(t) [in/s]. The block diagram should flow horizontally from inputs on the left to outputs on the right. 4. The outputs of interest for this system are the position, velocity, and acceleration of the mass, as well as the force in the spring. Output each of these values to the MATLAB workspace and generate a plot of each output with respect to time. Run the simulation for 15 [s]. T m k eee m b

2. (Chapter 3) Consider a transformer bank comprised of three single-phase transformers, 24.92-kV $\Delta$ / 288.7-kV Y, each rated at 1500 MVA, with leakage reactance $X_{eq} = 0.11$ p.u. Assume that winding resistance and exciting current are negligible. The high-voltage side is connected to a balanced load of 3000 MVA at 0.90 p.f. lagging, with $V_{AN} = 1.0\angle 0^\circ$ p.u. The low-voltage side is connected to a generator. Draw the per-unit equivalent circuit. Then calculate, in both per-unit and actual units: (a) The phase current on the high-voltage side. (b) The magnitude and angle of the voltage on the low-voltage side of the transformer. Be careful to account properly for the phase shift between Y and $\Delta$ voltages and currents.
