I think what Volv is trying to explain here is that the force of gravity has been restricted to that of the motion of the plane due to the slope being an immovable plane.

So when we measure Force along (parallel to) the plane, it becomes a component of the downwards force.

This is described in blessedguy's post as proportional to (cos A)*(mass of chain above BC) or Chancer's post as W sin ( a ).
(On the left hand side)
Both being the same thing really.

My previous post was showing the proportions of mass on either side as being proportional to the inverse of these values.
This shows no movement in the chain.


Been a while since I've done maths. Good brain exercise.
