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






2. 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.






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






4. A resource that is entered into a system.






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






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






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






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






9. 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.'






10. The capacity to do work or exert effort.






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






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






13. Someone who starts a business.






14. 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.






15. 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.






16. Stored energy or energy at rest.






17. 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.






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






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






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






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






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






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






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






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


26. The splitting of the nucleus of an atom.






27. 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.






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






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






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






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






32. Energy in motion.






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






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






35. The capacity to do work or exert effort.






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






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






38. Restriction or limit placed on a product.






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






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






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






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






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






44. Creating things through the process of planning.






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






46. 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.






47. A method of obtaining energy from waste products






48. The formal rules that guide the design process.






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






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