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:

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.]

Plot a stress $\to$ strain curve for a metal and explain.

Two different types of rubber are found to have the stress-strain curves as shown. Then:

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

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.
