SUMMARY
The discussion centers on calculating the frequency of undamped motion for an aircraft's landing gear system. The maximum force exerted during landing is 7500N, with a vertical spring stiffness of 600N/mm and a damping coefficient of 38 x 10^3 Ns/m. The correct formula for frequency (fn) is derived as fn = 1/2π * √(k/m), leading to a final calculation of 4.45 Hz after correcting the spring constant to 600,000 N/m. The mass of the system is calculated to be approximately 764.53 kg based on the force of gravity.
