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






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






4. Restriction or limit placed on a product.






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






6. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






7. The act of putting different things together to form a new product or idea.






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

9. The use of force to act on an object in order to move move the object in the same direction as the force.






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






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






12. 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.'






13. 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.






14. 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.






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






16. Current flow in which electrons move in only one direction.






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






18. The formal rules that guide the design process.






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






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






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. The use of computers in each stage of the design process.






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






24. 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.






25. The capacity to do work or exert effort.






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






27. 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.






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






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






30. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






31. Stored energy or energy at rest.






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






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






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






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






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






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






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






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






40. A method of obtaining energy from waste products






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






42. The basic framework of a system






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






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






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






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






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






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






49. A popular movement.






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