Question

The stress-strain graph for a metallic wire is shown at two different temperatures, T1 and T2 which temperature is high T1 or T2 ? (A) T1 > T2 (B) T2 > T1 (C) T1=T2 (D) None of these

The slope of stress-strain curve with strain axis gives the value In the above graph strain is taken along y-axis. Therefore the slope of graph at temperature T1 is less than the slope of graph at temperature T2. Now as we know with increase in temperature the value of modulus of elasticity decreases. Therefore temperature T1 is greater than temperature T2.

Q. The stress-strain graph for a metallic wire is shown at two different temperatures, $T_{1}$ and $T_{2}$ which temperature is high $T_{1}$ or $T_{2} ?$

$T_{1} > T_{2}$

$T_{2} > T_{1}$

$T_{1} = T_{2}$

None of these

Q. The stress-strain graph for a metallic wire is shown at two different temperatures, T1​ and T2​ which temperature is high T1​ or T2​?

T1​>T2​

T2​>T1​

T1​=T2​

None of these
