In reply to H LV's message of Sat, 18 Mar 2017 10:11:20 -0400: Hi Harry, AFAIK the forces involved are all conservative. That means that the change in energy is the same, irrespective of the path taken between endpoints. In short the energy difference is the same whether the "nut and bolt" are screwed together or hammered together. Obviously this is not the case for a real nut and bolt, i.e. the amount of friction involved changes depending on the path taken.
