DT Glossary

1. two or more atoms which are normally bonded together covalently (8)
4. the ability of a material to be drawn or extruded into a wie or other extended shape (9)
5. the costs that must be paid out before production starts, eg machinery; they do not change with the level of production (5, 5)
6. the reliance on the knowledge and the skills of an expert in the operation of the product (6, 9)
7. the carrying of a continuos thread back and forth acress a set of length-wise threads to form an interlaced fabric (7)

2. a measure of the degree of increase in dimensions when an object is heated; this cna be measured by an increase in length, area, volume. The expansivity can be measured as the fractional increase in dimension per Kelvin increase in temperature (7, 9)
3. an approach to manufacturing to production which uses less resources and causes less enviornmental damage than an alternative means which it is economicaly competitive (5, 10)
8. the smallest part of an element that can exist chemically (4)
9. A mixture that contains at least one metal. (5)
