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 judgement of the end result based upon given criteria.






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






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






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






5. The basic framework of a system






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






7. A resource that is entered into a system.






8. The capacity to do work or exert effort.






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






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






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






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






14. 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.






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






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






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






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






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






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






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






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






23. 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.






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






25. 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.






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






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






28. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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






38. Energy in motion.






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






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






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






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






43. 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.






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






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






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






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






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






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






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