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






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






3. Creating things through the process of planning.






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






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






6. Stored energy or energy at rest.






7. 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.






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






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






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






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






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






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






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






15. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






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






17. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






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






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






28. 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.'






29. The splitting of the nucleus of an atom.






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






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






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






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






34. The formal rules that guide the design process.






35. 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.






36. The capacity to do work or exert effort.






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






38. Someone who starts a business.






39. 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.






40. 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.






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






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






43. Energy in motion.






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






45. A popular movement.






46. 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.






47. A resource that is entered into a system.






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






49. 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.






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