Data: A chain (discrete catenary) has n links; mass and length of each link is known. One end of the catenary is fixed to the left pole. Massless rope of length l connects second end of the catenary and the second pole. Location and height of each pole is also given.
Questions: What are the magnitudes of forces that act upon links? What is the tension in the rope?
