Determine the principal coordinates for the system of Figure P6.1 and Chapter Problem 6.10. Write the differential equations which the principal coordinates satisfy.

Data From Chapter Problem 6.10:
Determine the natural frequencies of the system of Figure P6.1 if \(m=10 \mathrm{~kg}\) and \(k=1 \times 10^{5} \mathrm{~N} / \mathrm{m}\). Determine and graphically illustrate the mode shapes. Identify any nodes.
