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 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.






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






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






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






5. Someone who starts a business.






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






7. Stored energy or energy at rest.






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






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






10. 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.






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






12. The capacity to do work or exert effort.






13. 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.






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






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






16. A popular movement.






17. 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.






18. A resource that is entered into a system.






19. The splitting of the nucleus of an atom.






20. The formal rules that guide the design process.






21. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






30. The basic framework of a system






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






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. 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.'






34. Restriction or limit placed on a product.






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






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






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






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






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






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






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






42. Energy in motion.






43. A method of obtaining energy from waste products






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






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






46. 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.






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






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






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