Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A unit that collects waves and decodes information contained within those waves.






2. The use of lasers to record realistic images of three- dimensional objects.






3. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






4. The use of pressurized liquid or gasses to control and transmit power.






5. The act of breaking a particular subject into different parts to achieve clarity of understanding.






6. A device that orbits the Earth and receives messages from one location and transmits them to another.






7. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






8. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






9. A production system in which products are made one at a time according to customer's specifications.






10. The path by which a message travels from the sender to receiver.






11. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






12. Stored energy or energy at rest.






13. A group of people working together to accomplish a common goal.






14. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


15. The path by which electric current or pulses flow.






16. The technology field focused on sending messages and other in formation using different means.






17. The field of knowledge relating to materials as they exists on a molecular or atomic level.






18. The superimposition of sine waves on electromagnetic carrier waves.






19. A production process in which the part or product moves down a line from one station to the next while parts are added.






20. The splitting of the nucleus of an atom.






21. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






22. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






23. The use of a computer system to produce technical drawings and/or design a product.






24. The use of 3D CAD drawings to create real models of a product within a sort of time.






25. A method of obtaining energy from waste products






26. The unlawful acquisition of some one's personal information for use without their consent.






27. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






28. Studying the effects of a given technology to determine its impact.






29. The capacity to do work or exert effort.






30. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






31. A circuit in which electricity flows along more than one path.






32. A language - used to write computer programs - that can easily be translated into machine language.






33. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






34. The basic framework of a system






35. The money a business makes after all expenses have been paid






36. A popular movement.






37. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






38. Current flow in which electrons reverse direction at regular intervals.






39. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






40. The capacity to do work or exert effort.






41. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






42. Someone who starts a business.






43. A resource that is entered into a system.






44. The use of simple machines to multiply the output force of a mechanical system.






45. The judgement of the end result based upon given criteria.






46. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






47. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






48. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






49. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






50. Trade of products and services on a global scale.
