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
modulii of the materials, then

A$Y_{B} = 2Y_{A}$B$Y_{A} = Y_{B}$C$Y_{B} = 3Y_{A}$D$Y_{A} = 3Y_{B}$

Show answer and solution▾

$\frac{\ Stress\ }{\ Strain\ } = Y = \ slope\ of\ graph\$
