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. 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.






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






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






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






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






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






8. The formal rules that guide the design process.






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






10. Stored energy or energy at rest.






11. 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.






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






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






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






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






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






17. The capacity to do work or exert effort.






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






19. Someone who starts a business.






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






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






22. Energy in motion.






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






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






25. Restriction or limit placed on a product.






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






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






28. 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.






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






30. The capacity to do work or exert effort.






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






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






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






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






35. The basic framework of a system






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






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






38. A popular movement.






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






40. 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.






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






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






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






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






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






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






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






48. 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.






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






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