章节摘录

　　Mechanical properties mean a material's ability to carry or resist the application of mechanical forces and loads.The material's reaction to these forces is usually either deformation or fracture.Mechanical properties are probably the most important to manufacturing processing.They determine the extent to which a material may be formed， sheared， or machined.Typical forces which are applied to a material are tension， compression， shear， and torsion， these forces are used to form and shape materials. Furthermore， materials must withstand excess amounts of these forces in product applications. Since screws are used to assemble wood parts，" they must absorb torsion forces. Rods holding suspended fixtures must withstand excess tension forces.The head of a hammer must absorb compression forces.（1） Stress-strain. The stress-strain relationship is often used to study many mechanical properties. Stress is force applied to material. It is usually measured in either pounds per square inch or kilograms per square centimeter. Strain is the change in the length of a material which is under stress. The strain measurements are given in term of the amount of elongation of the material per unit of length. Strain is given in thousandths of an inch per inch of material of millimeters （of smaller units） per centimeter of material. For most materials， the elongation of a material under stress is quite small.　　……
