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






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






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






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


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






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






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






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 formal rules that guide the design process.






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






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






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






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






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






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






16. The splitting of the nucleus of an atom.






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






18. 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.






19. A popular movement.






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






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






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






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






24. The capacity to do work or exert effort.






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






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






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






28. 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.






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. The superimposition of sine waves on electromagnetic carrier waves.






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






32. 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.






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






34. Someone who starts a business.






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






36. The capacity to do work or exert effort.






37. Creating things through the process of planning.






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






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






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






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






42. Restriction or limit placed on a product.






43. Stored energy or energy at rest.






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






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






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






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






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






49. 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.






50. Energy in motion.
