What is the formula for force when a rod fixed between two rigid support at both end. A temperature is changed by

\Delta {T}, {Y}

-young modulus,

\boldsymbol{\alpha}=

coefficient of linear expension :

View answer and explanation

Correct option: A

F=Y A \alpha \Delta T

Option A (

F=Y A \alpha \Delta T

) is correct because it represents the thermal stress formula for a rod fixed between two rigid supports.
