Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 20 minutes. 1 minute extra for reading the instructions.
  • 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 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.






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






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


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






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






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






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






8. 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.






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






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






11. The basic framework of a system






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






13. Energy in motion.






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






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






16. Stored energy or energy at rest.






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






18. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






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






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






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






22. Someone who starts a business.






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






24. A resource that is entered into a system.






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






26. The splitting of the nucleus of an atom.






27. 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.






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






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






30. 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.






31. Restriction or limit placed on a product.






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






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






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






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






37. The capacity to do work or exert effort.






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






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






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






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






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






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






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. 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.






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






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






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






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






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