Hi Jim, What node points in a sine wave???? A sine wave by definition has a constant rate of change, therefore bending would imply something that is not constant!!!!! However I agree with the overall valuable contributions that you are making to this discussion, sure tell you worker around H.Conklin. A pity he is not here helping out' Regards Roger >If you simply look at the nodal point of any sine wave, the bending takes >place at the loops, not at the nodes. The nodes are the pivot points.
