Properties of materials

A property of a material describes its characteristics and distinguishes it from the others. The material properties are described it in terms of its hardness, color, appearances, and so on. The material properties generally depend on the type of material, or whether it is a metal or an alloy. There are different kinds of material properties such as mechanical properties, thermal properties, physical properties, and chemical properties. Chemical properties describe the material in terms of a chemical change. The mechanical properties come into existence when the material is acted upon by an external load. Thermal properties are associated with the temperature of the material and specific heat.

Calculate the S and Z values about the horizontal axis for the beam section shown below Hie To calculate Z, split the section into the top half and bottom half. Then identify the centroid ef each half and the distance between them. Then half of the area times this distance between t centroids gives you Z. To find S, simply find the moment of inertia and divide it by the die from neutral axis to the extreme fiber.
