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 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.






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






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






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






5. 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.






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






7. 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.






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






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






10. 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.'






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






12. A resource that is entered into a system.






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






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






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






16. The capacity to do work or exert effort.






17. 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.






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






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


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






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






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






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






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






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






27. Someone who starts a business.






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






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






30. 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.






31. 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.






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






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






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






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






36. The splitting of the nucleus of an atom.






37. A popular movement.






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






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






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






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






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






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






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






46. Creating things through the process of planning.






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






48. The capacity to do work or exert effort.






49. Restriction or limit placed on a product.






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