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 formal rules that guide the design process.






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






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






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






5. 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.






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






7. 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.






8. 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.






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






10. A method of obtaining energy from waste products






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






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






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






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






15. A popular movement.






16. A resource that is entered into a system.






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






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






19. The basic framework of a system






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


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






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






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






24. 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.






25. 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.






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






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






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






29. 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.






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






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






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






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






34. The splitting of the nucleus of an atom.






35. 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.






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






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






38. 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.






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






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






41. Stored energy or energy at rest.






42. The capacity to do work or exert effort.






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






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






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






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






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






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






49. Creating things through the process of planning.






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