Stress vs strain curve for the elastic tissue of the aorta, the large tube (vessel) carrying blood from the heart, will be : [stress is proportional to square of the strain for the elastic tissue of the aorta]
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.
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.
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 |
In the below graph, point $D$ indicates
Which one of the following is the Young’s modulus $($in $N/m^2)$ for the wire having the stress-strain curve shown in the figure
