Across
- 3. The part of a satellite communication link that goes from the ground station to the satellite. Together with the downlink this forms a complete satellite communication system.
- 5. The twisting or wrenching of a body by the exertion of forces tending to turn one end or part about a longitudinal axis while the other is held fast or turned in the opposite direction.
- 10. The technology of using the human voice as an input to phone, computer, or another machine. Examples include Siri, Alexa, Chromebooks, etc.
- 14. The part of a communication system that accepts the message from the originator and places it on the channel.
- 15. Human made; not occurring in nature. Synthetic motor oil is a good example of this.
- 19. The ability of a material to absorb shocks without breaking.
- 20. A smart home refers to a convenient home setup where appliances and devices can be automatically controlled remotely from anywhere with an internet connection using a mobile or other networked device.
- 25. Having to do with heat or the transfer of heat.
- 26. A container for transporting people, animals, or goods. Vehicles can operate on fixed routes (elevators, railroad trains, monorails, trolley cars) or random routes (bicycles, cars, trucks, airplanes, rockets, boats).
- 28. The period in which people used stones and other simple materials (wood and bone) to make tools and weapons. This happened in the middle east before 3000 BC.
- 29. A method of solving problems in which many solutions are tried until one is found to be acceptable.
- 30. Refers to the way in which all the parts of a design look as if they belong together and produce a single general effect.
Down
- 1. A system that, together with other subsystems, contributes to the functioning of the larger system,
- 2. A method of joining two wires, or two circuit board parts together by melting a metal called solder (lead and tin alloy) onto them.
- 4. A reciprocating engine having a piston driven in a closed cylinder by steam created from boiling water.
- 6. A force or action that stretches an object. Many bridge and construction pieces are put in tension.
- 7. The process of generating spoken language by machine based on written input.
- 8. An organization of working people joined together for common purposes, usually to maintain good working conditions. Many jobs have unions – Plumbers Union, Electrician’s Union, Nurse’s Union, Teacher’s Union, etc.
- 9. In construction, the part of the structure above the foundation. The superstructure is usually the part of the structure that is visible above the ground.
- 11. A three-terminal electronic component made of semi-conductor material. A transistor enables a small amount of electricity to control a large amount of electricity.
- 12. The force developed to move an airplane or rocket forward through the air.
- 13. An exchange of the benefits and disadvantages of one solution for those of another solution.
- 16. With machines, one of the seven resources used in technological systems. Tools extend the natural capabilities of people and are used to process or maintain other resources in systems.
- 17. A computer vastly superior in size and speed to the mainframe computers in use at any given time. Because of the rapid progress in computer technology, supercomputer performance of yesterday is commonplace today.
- 18. Something built or constructed on a construction site. Structures can include buildings, bridges, dams, tunnels, roads, airports, canals, harbors, pipelines, and towers.
- 21. A combination of things that act together in a more powerful way than each would act individually. Also, a way of achieving a desired result through the processing of resources in response to a command input. A system may be open-loop (no feedback) or closed-loop (using feedback).
- 22. Coming from or caused by the sun. Produced or operated by the action of the sun's light or heat.
- 23. The use of accumulated knowledge to process resources to satisfy human needs and wants.
- 24. To work at home using computers, terminals, and data communications rather than physically traveling to work. This has been used much more since the COVID pandemic.
- 27. When dealing with aeronautics, it is the downward force that acts on a plane or rocket. Lift is needed to overcome the force created by the weight.
