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






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






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






4. The basic framework of a system






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






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






7. The splitting of the nucleus of an atom.






8. Restriction or limit placed on a product.






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






10. The capacity to do work or exert effort.






11. 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.






12. Stored energy or energy at rest.






13. A popular movement.






14. A resource that is entered into a system.






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






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






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






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






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






21. 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.






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






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






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






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






26. Creating things through the process of planning.






27. The formal rules that guide the design process.






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






30. 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.'






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






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






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






34. 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.






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






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






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






38. The capacity to do work or exert effort.






39. Someone who starts a business.






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






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






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


43. 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.






44. Energy in motion.






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






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






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






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






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






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