Thermal Expansion of Solid Bodies

The expansion of materials due to temperature change is an important issue when designing structures or mechanical applications. The thermal expansion measurement device is designed to study the linear expansion of solid materials when subjected to temperature changes. By heating a specimen and recording its change in length, users can experimentally determine the coefficient of linear expansion for different materials. This apparatus provides a clear demonstration of this process, helping learners connect theoretical principles of heat transfer and material behavior with practical experimentation. It is widely used in educational laboratories for material science, physics, and engineering studies.
