This course serves as an introduction to the physical properties of materials. While the main focus of this course is on solid materials, properties of liquids and gases will also be presented at various points in the course – in particular in studying the thermal properties of materials and the phase changes from the solid to liquid state (melting/freezing) and from the liquid to gas state (evaporation/condensation). Students will study the properties of metals, ceramics, semiconductors, polymers, and composite materials. Topics include the mechanical, electrical, thermal, acoustic, optical, and magnetic properties of materials. The course includes an overview of the atomic theory of matter, the periodic table, the crystal structures of solids and the metallurgy of steels and non-ferrous metals. There is a strong lab component which includes experiments to measure the tensile strength and modulus of elasticity of steel, the modulus of rigidity of a steel shaft, the flexure of a centrally loaded beam, the specific heat capacity and thermal coefficient of linear expansion of copper and aluminum, the electrical resistivity of metals and semiconductors, the photoelectric effect, the cooling curves of low melting point alloys, the index of refraction of optically transparent materials, and the heat treatment of steels. These topics are introduced and explored through a series of standard, as well as microcomputer-based (MBL), labs using PASCO’s 750 Interface and DataStudio software.
