A uniform cylindrical rod of length L and radius r, is made from a material whose Young’s modulus of Elasticity equals Y. When this rod is heated by temperature T and simultaneously subjected to a net longitudinal compressional force F, its length remains unchanged. The coefficient of volume expansion, of the material of the rod, is (nearly) equal to: |

a) |
9F/( YT) |
b) |
3F/( YT) |

c) |
F/(3 YT) |
d) |
6F/( YT) |
