1 Properties of metals vary widely as a result of variations in composition, heat treatment, and mechanical working.
2 For ductile metals the compression strength is generally assumed to be equal to the tension strength.
3 Offset of 0.2 percent
4 Timber properties are for loading parallel to the grain. |
