Show, mathematically, that for a non-uniform cantilever beam, the unsupported boundary condition \frac{d}{dx} \left( EI(x) \frac{d^2y}{dx^2} \right) \Big|_{x=a} = 0 is equivalent (in terms of beam deflection) to the boundary condition $EI(a)y''(a) = 0$

Chlorine is prepared by oxidation of hydrogen chloride gas in the presence of a catalyst at 723K to produced chlorine and water, as shown below (not-balanced). HCl + O$_2$ ? Cl + 2H$_2$O The process is called Deacon's process. In such process, a sufficient amount of air is fed to provide oxygen; namely 50% excess oxygen and 95% fraction conversion of hydrogen chloride, a limiting reactant. Determine the following: a) Molar flowrate of the product stream components using atomic species balance (perform the degree of freedom analysis first) b) Composition of the output stream using extent of reaction method in your calculation c) How would your results in (a) would different if you solved the problem using molecular balance method? d) Minimum amounts of air required e) Minimum amounts of limiting reactant required to produce 152 moles/hr of chlorine f) Relation between extent of reaction and limiting reactant conversion

During the past year a company had total fixed costs of $700,000. Its product sold for $93 per unit. Variable costs during this time equaled $45 per unit. Next year the company is anticipating a 10% increase in total fixed costs and a $3 per unit decrease in variable costs, but would like to maintain its current selling price per unit. How many units must the company sell next year to earn $1,000,000? (Round answer to complete units.)

Write a Matlab program to plot the following function in the frequency domain: $G(f) = AT \frac{\sin(\pi fT)}{\pi fT} = AT \text{sinc}(fT)$ where $A$ and $T$ are two parameters and we have $A > 0$ and $T > 0$. Special requirements: \begin{itemize} \item The plot should contain the mainlobe and six sidelobes on both sides, no more, no less. \item Do not use the sinc function in Matlab. \item Your matlab program should provide a meaningful output for $G(0)$. \item Change your $A$ and $T$, show a few examples of different combinations of the parameters. \end{itemize}
