To understand the concept of tension and the relationship
between tension and force.This problem introduces the concept of tension. The example is a
rope, oriented vertically, that is being pulled from both ends.
(Figure 1) LetFu and Fd (with u for up and d for down)
represent the magnitude of the forces acting on the top and bottom
of the rope, respectively. Assume that the rope is massless, so
that its weight is negligible compared with the tension. (This is...
