Ten Meter Great White Sharks Tension In A Massless Rope?

Tension in a Massless Rope? - ten meter great white sharks

The example is a rope, a vertical orientation, ie, pulled at both ends. And either (or up and down d) the extent of the forces on the top and bottom of the rope, respectively. Let us assume that the string has no mass, so that their weight is negligible compared to the tensions. (This is not a ridiculous approach - the string of modern materials like Kevlar tension can lead to thousands of times more so than the weight of several tens of meters of rope.)
Consider the three sections of rope labeled A, B and C in Fig.

In Section 1, a downward force is the size of the Section A
In Section 1, an upward force of the magnitude of effect in Section B.
In Section 1, the chain tension.
In Section 2, a downward force affects the size in Section B.
In Section 2, an upward force acts in the scope section C.
In Section 2, the chain tension.


Suppose further that the rope is in equilibrium.

Give your answer in terms of stress.
