QUESTION 4:(25pts) The Simulink diagram shown is built to simulate the response of the following coupled system of equations $\ddot{x} + 2\mu \dot{x} + \omega_n^2 x - \theta y = xP \cos(\Omega t)$ $\frac{1}{R} \dot{x} + \theta \dot{x} = 0$ $C_p \dot{y} + \frac{y}{R} + \theta \dot{x} = 0$ $x(0) = 0, \dot{x}(0) = 1, y(0) = 0.1$ where the states are $x$ and $y$ and the rest are constants given as $\mu = 0.02, \omega_n = 1, \theta =$ $0.1, P = 4, \Omega = 2, R = 10000$, and $C_p = 0.00001$. Complete the following: 1. Connect all the disconnected arrows in the figure. (6pts) 2. Find the value of all the gains (pay attention to the signs). (10pts) 3. On the graph, show where would you add scopes to view $\dot{y}$ and $x$. (4pts) 4. On the graph, show how would you add the nonlinearity $0.1x^3$ to the right hand side of the first equation. (5pts)

Read the quotation about a vision for American society after the American Revolution. "This Sir, was a time in which you clearly saw into the injustice of a State of Slavery, and in which you had just apprehensions of the horrors of its condition, it was now Sir, that your abhorrence thereof was so excited, that you publickly held forth this true and invaluable doctrine, which is worthy to be recorded and remember'd in all Succeeding ages. 'We hold these truths to be Self evident, that all men are created equal, and that they are endowed by their creator with certain unalienable rights, that among these are life, liberty, and the pursuit of happyness." To whom is the speaker writing?

A 0.4 kg ball with a radius of 0.2 meters (thin-walled hollow sphere with Icom=(2/3)MR^2) is initially moving to the left at 4 m/s. If it rolls without slipping the entire time, calculate the change in height of the ball's center of mass from its initial position to the highest point the ball reaches before rolling back down. Use 10 N/kg for g and enter your answer in units of meters rounding to two decimal places. Your Answer:

Question 32 1pts Initial encounter for displaced fracture of shaft of left clavicle as the result of a fall while snowboarding down a mountain. ◻ Note: of the five codes, one is primary and must be listed first. The remaining codes do not require order specificity. Also, pay attention to the guidelines for Chapters 19 & 20. Be CAREFUL that you do not enter the same code twice.

4. (24 pts) Lattice Vibration. Consider a 1D atomic chain of identical atoms of mass M. The interatomic interactions are between all pairs of atoms, rather than between the nearest neighbor atoms only. Thus, the elastic potential energy can be expressed as \begin{equation} V = \frac{1}{2} \sum_{n} \sum_{m \neq 0} C_m (u_n - u_{n+m})^2 \end{equation} where $u_n$ is the displacement of atom $n$. Assuming the distance between the nearest neighbor atoms is $a$. a) Find the dispersion relation, i.e. the vibrational frequency $\omega$ as a function of the wavenumber $K$. b) Assume $C_m = C_0/m^p$, where $p > 1$ is a parameter controlling how rapidly the interactions drops off with distance. Study the long-wavelength limit (when $Ka << 1$) of the dispersion relation for $p > 3$. Determine the sound velocity. Note: It is not necessary to find the analytical expression for the infinite series.
