In Column$-I$ there are two graphs and in Column$-II$ whose graph is for this are given. Join them appropriately :

Column $-I$	Column $-II$
$(a)$ image	$(i)$ $A$ is ductile
$(b)$ image	$(ii)$ $A$ is brittle
	$(iii)$ $B$ is ductile
	$(iv)$ $B$ is brittle

A student plots a graph from his reading on the determination of Young’s modulus of a metal wire but forgets to label. The quantities on $X$ and $Y$ axes may be respectively.

The load versus strain graph for four wires of the same material is shown in the figure. The thickest wire is represented by the line

Which of the following is the graph showing stress-strain variation for elastomers?

The diagram shows the change $x$ in the length of a thin uniform wire caused by the application of stress $F$ at two different temperatures $T_1$ and $T_2$. The variations shown suggest that

The stress versus strain graphs for wires of two materials $A$ and $B$ are as shown in the figure. If ${Y_A}$ and ${Y_B}$ are the Young ‘s modulii of the materials, then
