Fixture : It is a device which is used to hold objects in place and clamp them to machines or operating surfaces, so that the object can be machined or assembled.

Flagpole : It is rising from the ground and on which flags or other signals are displayed. On charts this term is used onlt when the pole is not attached to a building.

Foundry and Production Technology

Fuel : It is a material which is burned or altered in order to obtain energy. Its energy can be stored to be released only when required and that the release is controlled in such a way that the energy can be harnessed to produce work.
  • Solid Fuels : These are used as fuel to produce energy and provide heating, usually released through combustion. For example, wood, lignite, coal, peat, etc.

  • Liquid Fuels : Derivatives of natural petroleum, petrol, diesel, etc.

  • Gaseous Fuels : It is a combustible gas that can be burned in a furnace or an engine. For example natural gas, coal gas, etc.
