How to get the uncoupled natural frequencies
Hello Everybody,
A wing was simplified with 8 dumbbelss or concentrated mass. The weight of the 8 dumbbells are:
{W}=[1.240 1.050 0.964 0.862 0.733 0.628 0.634 0.457]T
The static unbalance is:
{SA}=[0.2680 0.2910 0.1810 0.1610 0.1220 0.0884 0.0854 0.0598]T
The moment of inertia is:
{IA}=[0.412 0.437 0.272 0.230 0.157 0.143 0.115 0.055]T
