GATE ME 2014 Set 2

MCQ (Single Correct Answer)

-0.3

A steel cube, with all faces free to deform, has Young’s modulus, $$E,$$ Poisson’s ratio, $$ν,$$ and coefficient of thermal expansion, $$\alpha .$$ The pressure (hydrostatic stress) developed within the cube, when it is subjected to a uniform increase in temperature, $$\Delta T,$$ is given by

$$0$$

$${{\alpha \left( {\Delta T} \right)E} \over {1 - 2v}}$$

$$ - {{\alpha \left( {\Delta T} \right)E} \over {1 - 2v}}$$

$${{\alpha \left( {\Delta T} \right)E} \over {3\left( {1 - 2v} \right)}}$$
