Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world or the Blue Planet.
Enginehouse pertains to a building in which locomotives are serviced - repaired or cleaned, and/or stored.
Deutsch: Ingenieurwissenschaften / Español: Ingeniería / Português: Engenharia / Français: Ingênierie / Italiano: Ingegneria
Engineering is the application of scientific, economic, social, and practical knowledge in order to design, build, and maintain structures, machines, devices, systems, materials and processes. It may encompass using insights to conceive, model and scale an appropriate solution to a problem or objective. The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of technology and types of application.
Deutsch: Umgebung / Español: Problema ambiental / Português: Ambiente / Français: Environnement (homonymie) / Italiano: Ambiente
Environment may refer to the physical and biological factors along with their chemical interactions that affect an organism or the surroundings of a physical system that may interact with the system by exchanging mass, energy, or other properties.
Deutsch: Motor / Español: Motor / Português: Motor / Français: Moteur / Italiano: Motore
An engine or motor is a machine designed to convert energy into useful mechanical motion. Heat engines, including internal combustion engines and external combustion engines (such as steam engines) burn a fuel to create heat, which then creates motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others such as clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create motion.
Enclosed laser device is defined as any laser or laser system located within an enclosure which does not permit hazardous optical radiation emission from the enclosure. The laser inside is termed an embedded laser.
