Figure 2.98 shows a spacecraft with four solar panels. Each panel has the dimensions \(1.5 \mathrm{~m} \times 1 \mathrm{~m} \times 0.025 \mathrm{~m}\) with a density of \(2690 \mathrm{~kg} / \mathrm{m}^{3}\) and is connected to the body of the spacecraft by aluminum rods of length \(0.3 \mathrm{~m}\) and diameter \(25 \mathrm{~mm}\). Assuming that the body of the spacecraft is very large (rigid), determine the natural frequency of vibration of each panel about the axis of the connecting aluminum rod.
