We know that if a rigid body is rotating simultaneously about two lines which intersect, the angular velocity is the vector sum of the two angular velocities around the two lines, respectively. I have some difficulty in imagining such a simultaneous rotation, do you know is there any video in internet that shows such a rotation in a clear way? Thanks a lot.

However, if there's torque, the vector describing the resultant angular velocity vector changes. If the torque varies, you might get a situation where the rotational plane will constantly change. Try looking up videos of gimbals or gyroscopes.

I haven't watched this full video, but I know Eugene Khutoryansky has some solid videos on aiding in visualizing concepts in physics. Especially more challenging concepts. Perhaps this will help:
