Application +4 | -1

There is some change in length when 33000 N tensile force is applied on a steel rod of area of cross section

{10^{ - 3}}{m^2}

. The change in temperature required to produce the same elongation of elasticity is

3 \times {10^{11}}\,N/{m^2}

and the co-efficient of linear expansion of steel is

1.1 \times {10^{ - 5}}/{\,^ \circ }C

View answer and explanation

Correct option: C

{10^ \circ }C

Option C (

{10^ \circ }C

) is correct because it is the temperature change calculated using the relationship between tensile force, Young's modulus, area, and coefficient of linear expansion.
