#### Description

When heated, metals expand. If they are not given space to expand, an internal force and thus stress is caused. This project is the design of a physical experiment demonstrating this interface of the fundamental principles of heat transfer and mechanics of materials. The principle in heat transfer is the concept of thermal expansion which states that expansion (or contraction) is directly related to initial length, type of material, and temperature change. The principle in mechanics of materials is the concept of axial stress and how it is caused by axial strain. The poster will show the physical set up of the student designed experiment, the mathematical verification of the physical principles, and a statistical analysis of the data.
