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. Stored energy or energy at rest.






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






3. 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.'






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






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


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






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






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






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






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






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






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






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






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






15. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






16. Creating things through the process of planning.






17. Someone who starts a business.






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






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






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






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






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






23. Energy in motion.






24. The splitting of the nucleus of an atom.






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






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






27. The capacity to do work or exert effort.






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






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






30. 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.






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






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






33. 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.






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






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






36. 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.






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






38. 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.






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






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






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






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






43. Restriction or limit placed on a product.






44. 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.






45. 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.






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






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






48. 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.






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






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