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






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






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






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






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






6. 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.'






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






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






9. Energy in motion.






10. 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.






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






12. A method of obtaining energy from waste products






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






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






15. 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.






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






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






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






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






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


21. Creating things through the process of planning.






22. 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.






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






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






25. 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.






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






27. Restriction or limit placed on a product.






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






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






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






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






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






33. The formal rules that guide the design process.






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






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






36. The splitting of the nucleus of an atom.






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






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






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






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






41. The basic framework of a system






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






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






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






45. The capacity to do work or exert effort.






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






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






48. Stored energy or energy at rest.






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






50. 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.
