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 pressurized liquid or gasses to control and transmit power.






2. 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.






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






4. 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.






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






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






7. A method of obtaining energy from waste products






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






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






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






11. 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.






12. 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.






13. 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.






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






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






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






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






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






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






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






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






22. The formal rules that guide the design process.






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






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






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






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






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






30. Creating things through the process of planning.






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






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






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






34. A resource that is entered into a system.






35. The splitting of the nucleus of an atom.






36. Stored energy or energy at rest.






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






38. The capacity to do work or exert effort.






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






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






41. 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.






42. 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.'






43. 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.






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






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






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






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






48. A popular movement.






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






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