[問題] 跟Lagrangian 及principal moments有關的問題,感謝
有兩個問題想請問各位物理強者!
1.Find the normal coordinates of the system with Lagrangian
L = 0.5*(x'^2+y'^2)-0.5*(x^2+4*y^2)+α*x*y
2.Show that the principal moments of inertia of
any body satisfy the triangle inequalities:
I3≦I1 + I2, I2≦I1 + I3, I1≦I2 + I3,
and that equality holds only for a planar body
先感謝物理超男子大大們~
