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






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






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






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






6. 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.






7. 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.






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






9. The splitting of the nucleus of an atom.






10. Creating things through the process of planning.






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






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






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






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


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






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






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






18. The number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.






19. 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.






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






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






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






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






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






25. The capacity to do work or exert effort.






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






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






29. 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.






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






31. Restriction or limit placed on a product.






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






33. Someone who starts a business.






34. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






43. A resource that is entered into a system.






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






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






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






47. 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.






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






49. Energy in motion.






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