4. Peak to Average Power. A cylindrical nuclear reactor has an axial (z-axis) power profile given by: $q'(z) = q'_{\max} \cos \left( \frac{\pi z}{H_2} \right) \text{ W/cm,}$ where $-\frac{H_1}{2} \leq z \leq +\frac{H_1}{2}$. The two dimensions given are related by $H_1 = 0.95H_2$, and total power is $Q_{tot} = q'_{avg} \cdot H_1$. Determine the ratio of $\frac{q'_{\max}}{q'_{avg}}$ (known as an axial hot channel factor).

During the static test of an aircraft panel, three strain gauges of 240 $\Omega$ each and 2.1 gauge factor, are used to measure the strains at a point on the free surface. It is found that the induced changes in the resistances of these gauges are: - 0.2008 $\Omega$ - 0.252 $\Omega$ and + 0.1008 $\Omega$ for gauges at angle (a) 0°, (b) 120° and (c) 240° respectively. If the panel is made of Aluminum with E=70GPa and v = 0.28; Determine: i. The principal strains and their directions. [5 Marks] ii. The maximum shear strain and associated average normal strain. [2 Marks] iii. The principal stresses. Sketch the results on properly oriented element. [3Marks] iv. The maximum shear stress and associated average normal stress. Sketch the results on properly oriented elements. [3 Marks] v. The strain read by a strain gauge placed at 70° to the first strain gauge. [2 Marks]
