quantum mechanics - Rotation operator



The problem is this: Consider the operator eiπLy2. If you apply it to an eigenstate of L2 and Lx with l=1, prove that the resulting state is an eigenstate of Lz.


The idea is this: Lz(eiπLy2Y1,m)=iφ(eiπLy2Y1,m)=...=22(eiπLy2Y1,m).


But I don't know how to move from one equation to the other. I would appreciate any help. Thank you.

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
