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






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






3. The basic framework of a system






4. The formal rules that guide the design process.






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






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






7. Creating things through the process of planning.






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






9. 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.






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






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






12. 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.






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






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






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






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






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






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






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






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






22. 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.'






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






24. A method of obtaining energy from waste products






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






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






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






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


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






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






31. 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.






32. 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.






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






34. 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.






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






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






37. The splitting of the nucleus of an atom.






38. The capacity to do work or exert effort.






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






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






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






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






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






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






45. The capacity to do work or exert effort.






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






47. Someone who starts a business.






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






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






50. Energy in motion.
