ENGINEERING
An inverted pendulum mounted on a motor-driven cart. The nonlinear state-space equations representing that system were linearized around a stationary point corresponding to the pendulum point-mass, m, being in the upright position (x$_{0}$ = 0 at t = 0), when the force applied to the cart was zero (u$_{0}$ = 0). The state-space model developed in that problem is $$ \dot{\mathbf{x}}=\mathbf{A} \mathbf{x}+\mathbf{B} u $$ The state variables are the pendulum angle relative to the y-axis, $\theta,$ its angular speed, $\theta^{\prime},$ the horizontal position of the cart, x, and its speed, $x^{\prime}$. The horizontal position of m (for a small angle, $\theta$), $$ x_{m}=x+l \sin \theta=x+l \theta, $$ was selected to be the output variable. Given the state-space model developed in that problem along with the output equation you developed in that problem, use MATLAB (or any other computer program) to find and plot the output, x$_{m}$(t), in meters, for an input force, u(t) equal to a unit impulse, $\delta$(t), in Newtons.
ENGINEERING
Spur-gear teeth have rolling and slipping contact (often about 8 percent slip). Spur gears tested to wear failure are reported at $10^{8}$ cycles as Buckingham's surface fatigue load-stress factor K. This factor is related to Hertzian contact strength $\mathcal{S}_{C}$ by $S_{C}=\sqrt{\frac{1.4 K}{\left(1 / E_{1}+1 / E_{2}\right) \sin \phi}}$ where $\varphi$ is the normal pressure angle. Cast iron grade 20 gears with $\phi=14 \frac{1}{2}^{\circ} \text { and } 20^{\circ}$ pressure angle exhibit a minimum Kof 81 and 112 psi, respectively. How does this compare with $S_{C}=0.32 \mathrm{H}_{B} \mathrm{kpsi}$?
ENGINEERING
In 2001, the United States produced 51 percent of its electricity in the amount of $1.878 \times 10^{12} \mathrm{kWh}$ from coalfired power plants. Taking the average thermal efficiency to be 34 percent, determine the amount of thermal energy rejected by the coal-fired power plants in the United States that year.
ENGINEERING
Air within a piston-cylinder assembly, initially at $30 lbf/in.^2, 510^\circ R,$ and a volume of $6 ft^3,$ is compressed isentropically to a final volume of $1.2 ft^3.$ Assuming the ideal gas model with k = 1.4 for the air, determine the (a) mass, in lb, (b) final pressure, in $lbf/in.^2,$ (c) final temperature, in $^\circ R,$ and (d) work, in Btu.
