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 circuit in which electricity flows along more than one path.






2. Someone who starts a business.






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






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






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






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






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






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






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






10. 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.






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






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






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






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






15. 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.






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






17. 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.






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






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






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






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






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






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






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






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






26. A resource that is entered into a system.






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






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 splitting of the nucleus of an atom.






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






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


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






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






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






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






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






37. 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.






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






39. 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.






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






41. Creating things through the process of planning.






42. 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.






43. Restriction or limit placed on a product.






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






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






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






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






48. 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.






49. 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.






50. The formal rules that guide the design process.
