A large cylindrical tank contains 0.750 m3 of nitrogen gas at 27°C and 7.50 * 103 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.410 m3 and the temperature is increased to 157°C?

4. The fixed-point iteration method to find the root of an equation has the follow scheme $x_{i+1} = g(x_i)$, where $x = g(x)$ is derived from $f(x) = 0$. An improved fixed-point iteration scheme can be proposed as follows $y_i = g(x_i)$, $z_i = g(y_i)$, and $x_{i+1} = x_i - \frac{(y_i - x_i)^2}{z_i - 2y_i + x_i}$. Modify the given M-file function FixedPointIter.m and create a new M-file function FixedPointAcc.m by implementing the improved fixed-point iteration method. Test the new function with the example problem given in the lecture, that is to locate the root of $f(x) = e^x - x$. Compare your iteration results with the ones yielded from the conventional fixed-point iteration method. You can assume $x_0 = 0$, $g(x) = e^{-x}$ and $\varepsilon_s = 0.1\%$. [20 pts]

"; cin >> n; while (n > 0) { cout << "Enter a number: "; cin >> x1; sum = sum + x1; n = n - 1; } if (sum < 20) cout << "C++ is Great!" << endl; else { sum = sum - 2; cout << "I love C++." << endl; } }

a) Steel thin walled tube Figure 1 loaded in torsion as shown in the figure. The tube has a wall thickness of 6mm and 1.5 m long and has a maximum allowable shear stress of 80 MPa. Determine the maximum torque that can be applied and the corresponding angle of twist of the tube. $G = 79.3GPa$ b) Thin steel section Figure 2 has modulus of rigidity of 79.3GPa and allowable shear stress of 82.7 MPa. Determine the torque that applied on the section. $C1 = 2mm, C2 = 6mm$
