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. The superimposition of sine waves on electromagnetic carrier waves.






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






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






4. Energy in motion.






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






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






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






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






9. 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.'






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






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






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






13. 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.






14. Restriction or limit placed on a product.






15. Someone who starts a business.






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

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






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






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






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






21. 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.






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






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






24. The capacity to do work or exert effort.






25. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






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






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






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






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






30. Stored energy or energy at rest.






31. The splitting of the nucleus of an atom.






32. The basic framework of a system






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






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






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






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






37. Creating things through the process of planning.






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






39. 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.






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






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






42. A method of obtaining energy from waste products






43. 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.






44. 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.






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






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






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






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. A resource that is entered into a system.






50. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.
