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






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






3. 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.






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. Standards that a product must meet to be accepted.






6. Someone who starts a business.






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






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






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






10. A popular movement.






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






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






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






14. The basic framework of a system






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






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






17. 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.






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






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






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






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






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






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






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






25. 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.






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






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






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






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






30. A resource that is entered into a system.






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






32. 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.






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






34. Stored energy or energy at rest.






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


36. 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.






37. Restriction or limit placed on a product.






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






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






40. 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.






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






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






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






44. A method of obtaining energy from waste products






45. 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.






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






47. The capacity to do work or exert effort.






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






49. The capacity to do work or exert effort.






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