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
$III$ only
$II$ and $III$
$I$ and $III$
$I$ only
In the below graph, point $D$ indicates
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 modulus of the materials, then
The stress-strain curves for brass, steel and rubber are shown in the figure. The lines $A, B$ and $C$ are for
The adjacent graph shows the extension $(\Delta l)$ of a wire of length $1m$ suspended from the top of a roof at one end with a load $W$ connected to the other end. If the cross sectional area of the wire is ${10^{ - 6}}{m^2},$ calculate the young’s modulus of the material of the wire
Auniform rod rotating in gravity free region with certain constant angular velocity. The variation of tensile stress with distance $x$ from axis of rotation is best represented by which of the following graphs.
