In the below graph, point $B$ indicates
Breaking point
Limiting point
Yield point
None of the above
The diagram shows stress v/s strain curve for the materials $A$ and $B$. From the curves we infer that
The stress-strain graphs for materials $A$ and $B$ are shown in Figure
The graphs are drawn to the same scale.
$(a)$ Which of the materials has the greater Young’s modulus?
$(b)$ Which of the two is the stronger material?
A graph is shown between stress and strain for a metal. The part in which Hooke's law holds good is
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 uniform dense rod with non uniform young's modulus is hanging from ceiling under gravity. If elastic energy density at every point is same then young's modulus with $x$ will change as which of the shown graph
