R84 R110 Pins 21° 80 135° Hydraulic system Brake lining The Figure above shows an internal-expanding shoe brake system, actuated by a hy- draulic piston that exerts the force $P_a$ on each shoe. The identical shoes have a face width of 42mm. The lining material has a coefficient of friction of 0.34 and can take a maximum pressure of 1000k $P_a$. Determine (a) the allowable actuating force, (b) the braking torque capacity, and (c) the hinge-pin reactions.

The elasticity of production measures the percentage change in output (y) in response to a percentage change in one of the input factors. In this case, you're looking for the elasticity of production with respect to x 1 x 1 when x 1 = 2 x 1 =2 and x 2 = 2 x 2 =2 in the function y = x 1 2 / 5 x 2 3 / 5 y=x 1 2/5 x 2 3/5 .

Q6. The pressure $p$ and volume $v$ of a gas are believed to be related by a law of the form $p = Cv^n$, where $C$ and $n$ are constants. Experimental values of $p$ and corresponding values of $v$ obtained in a laboratory are: \begin{tabular}{|c|c|} \hline $p$ (Pa) & $v(m^3)$ \\ \hline 2.28$\times$10$^5$ & 3.2$\times$10$^{-2}$ \\ 8.04$\times$10$^5$ & 1.3$\times$10$^{-2}$ \\ 20.3$\times$10$^6$ & 6.7$\times$10$^{-3}$ \\ 5.05$\times$10$^6$ & 3.5$\times$10$^{-3}$ \\ 1.82$\times$10$^7$ & 1.4$\times$10$^{-3}$ \\ \hline \end{tabular} Verify that the law is true and determine approximate values of $C$ and $n$.
