| Zinc | (english) Chemical Symbol Zn. Element No. 30 of the periodic system; atomic weight 65.38. Blue-white metal; when pure, malleable and ductile even at ordinary temperatures; melting point 787 (degrees) F.; boiling point 1665 (degrees) F., specific gravity 7.14. Can be electrodeposited; it is extensively used as a coating for steel and sheet zinc finds many outlets, such as dry batteries, etc. Zinc-base alloys are of great importance in die casting. Its most important alloy is brass. |
| Zircon | (english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries. |
| Zirconia | (english) ZrO2 an acid refractory up to 2500 B0C (4532 B0F) having good thermal shock resistance and low electrical resistively. |
| Zirconium | (english) Silvery-white, metallic element, mp 1860 B0C (3380 B0F), a powerful deoxidizer when added to molten steel. |

| Acceleration: | (english) A vector quantity equal to the rate that velocity changes with time. |
| Axial force: | (english) A system of internal forces whose resultant is a force acting along the longitudinal axis of a structural member or assembly. |
| Bending moment: | (english) A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams. |
| Body force: | (english) An external force acting throughout the mass of a body. Gravity is a body force. An inertial force is a body force. |
