The stress-strain curves for brass,steel,and rubber are shown in the figure. The lines $A, B,$ and $C$ correspond to:

The diagram shows a force-extension graph for a rubber band. Consider the following statements:
$I.$ It will be easier to compress this rubber than expand it.
$II.$ Rubber does not return to its original length after it is stretched.
$III.$ The rubber band will get heated if it is stretched and released.
Which of these can be deduced from the graph?

Assertion $(A)$: Ductile metals are used to prepare thin wires.
Reason $(R)$: In the stress-strain curve of ductile metals,the length between the points representing elastic limit and breaking point is very small.

The graph below represents a typical stress-strain curve for a metal. Identify the point on the graph that is the ultimate tensile strength of the material.

The stress vs. strain curve for the elastic tissue of the aorta,the large tube (vessel) carrying blood from the heart,will be: [Note: Stress is proportional to the square of the strain for the elastic tissue of the aorta.]

The graph is drawn between the applied force $F$ and the strain $(x)$ for a thin uniform wire. The wire behaves as a liquid in the part:
