Your string and weight example is a demonstration of the conservation of angular momentum...not Coriolis Effect ! (or possibly the Red effect)
Hmm here we go again, the old bookshelf, rummage rummage, oh yes here we are, dust an all. Not the first one I owned someone stole that, this is a 1979 model but still word for word the original.
FAA Basic Helicopter Handbook p 14/15, a couple of excerpts.
“Coriolis Effect, when the blade of a three bladed rotor system flaps upward, the centre of mass of that blade moves closer to the axis of rotation and blade acceleration takes place and conversely.....To a lesser extent in a two bladed system when it is underslung....
The tendency of a rotor system to increase or decrease its velocity in its plane of rotation due to mass movement is known as Coriolis Effect, named for the mathematician who made studies of forces generated by radial movements of mass on a rotating plane...”
Of course formulae for the conservation of angular momentum follows.
More red please.
