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






2. Someone who starts a business.






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






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






5. Energy in motion.






6. 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.






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






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






9. The splitting of the nucleus of an atom.






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






11. The formal rules that guide the design process.






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






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






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






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






16. 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.






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






18. 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.






19. The capacity to do work or exert effort.






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






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






22. 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.






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






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






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






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






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






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






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






30. 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.






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






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






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






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






36. 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.






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


38. Creating things through the process of planning.






39. Restriction or limit placed on a product.






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






41. Stored energy or energy at rest.






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






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






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






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






47. The capacity to do work or exert effort.






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






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






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