The diagram shows stress v/s strain curve for the materials $A$ and $B$. From the curves we infer that
$A$ is brittle but $B$ is ductile
$A$ is ductile and $B$ is brittle
Both $A$ and $B$ are ductile
Both $A$ and $B$ are brittle
The value of force constant between the applied elastic force $F$ and displacement will be
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
The load versus elongation graph for four wires of the same material is shown in the figure. The thickest wire is represented by the line
A graph is shown between stress and strain for a metal. The part in which Hooke's law holds good is
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
