							The boy left holding the rod by one end feels two reactions. One is a doubling of the downward force on his hand from W/2 to W, and the other is a moment (torque) equal to W x L/2. Of course both reactions are not instantaneous, since the reactions travel at the speed of sound in the material of the rod
