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






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






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






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






5. Energy in motion.






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






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






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






9. A method of obtaining energy from waste products






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






11. The basic framework of a system






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






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






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






15. The capacity to do work or exert effort.






16. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






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






25. 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.






26. The capacity to do work or exert effort.






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






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






29. 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.






30. Restriction or limit placed on a product.






31. 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.






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






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






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


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






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






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






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






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






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






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 popular movement.






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






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






45. Creating things through the process of planning.






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






47. The formal rules that guide the design process.






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






49. 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.






50. Someone who starts a business.
