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 splitting of the nucleus of an atom.






2. A popular movement.






3. Energy in motion.






4. 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.






5. 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.






6. 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.






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






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






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






10. 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.






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


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






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






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






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






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






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






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






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






20. 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.






21. Restriction or limit placed on a product.






22. The formal rules that guide the design process.






23. A resource that is entered into a system.






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






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






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






27. The capacity to do work or exert effort.






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






29. A method of obtaining energy from waste products






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






31. 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.






32. 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.'






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






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






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






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






37. 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.






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






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






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






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






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






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






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






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






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






47. Stored energy or energy at rest.






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






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






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