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. 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.'






2. The capacity to do work or exert effort.






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






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






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






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






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






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






9. The splitting of the nucleus of an atom.






10. A group of people working together to accomplish a common goal.






11. 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.






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






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






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






15. The basic framework of a system






16. Stored energy or energy at rest.






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






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






19. Someone who starts a business.






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






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






22. 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.






23. 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.






24. A resource that is entered into a system.






25. Creating things through the process of planning.






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






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






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






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






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






31. Energy in motion.






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






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


34. The formal rules that guide the design process.






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






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






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






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






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






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






41. The capacity to do work or exert effort.






42. A method of obtaining energy from waste products






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






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






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






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






47. 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.






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






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






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