The diagram shows the stress versus strain curve for materials $A$ and $B$. From the curves,we infer that:

In the below graph,point $B$ indicates

Plot a stress $\to$ strain curve for a metal and explain.

The diagram shows the stress versus strain curve for materials $A$ and $B$. From the curves,we can infer that

The stress-strain curves are drawn for two different materials $X$ and $Y$. It is observed that the ultimate strength point and the fracture point are close to each other for material $X$ but are far apart for material $Y$. We can say that materials $X$ and $Y$ are likely to be (respectively)

The stress-strain graph of two wires $A$ and $B$ is shown in the figure. If $Y_{A}$ and $Y_B$ are Young's moduli of materials of wires $A$ and $B$ respectively, then
