STATEMENT - 1 : A metallic rod placed upon smooth surface is heated. The strain produced is ZERO.
STATEMENT - 2 : Strain is non-zero only when stress is developed in the rod.
STATEMENT - 3 : Two metallic rods of length `l_(1)` and `l_(2)` and coefficient of linear expansion `alpha_(1)` and `alpha_(2)` are heated such that the difference of their length ramains same at ALL termperatures Then `(alpha_(1))/(alpha_(2))=(l_(2))/(l_(1))`
