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 group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






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






3. The process of turning abstractions of thought into concrete ideas.






4. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






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


6. 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.






7. The capacity to do work or exert effort.






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






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






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






11. 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.'






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






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






14. 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.






15. 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.






16. A resource that is entered into a system.






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






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






19. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






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






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






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






23. A circuit in which electricity flows along a single path to more than one device.






24. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






25. The basic framework of a system






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






27. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






28. The formal rules that guide the design process.






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






30. Restriction or limit placed on a product.






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






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






33. The capacity to do work or exert effort.






34. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






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






36. A unit that collects waves and decodes information contained within those waves.






37. Someone who starts a business.






38. Creating things through the process of planning.






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






40. Energy in motion.






41. Stored energy or energy at rest.






42. Standards that a product must meet to be accepted.






43. The splitting of the nucleus of an atom.






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






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






46. 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.






47. A popular movement.






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






49. 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.






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