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 path by which electric current or pulses flow.






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






3. The splitting of the nucleus of an atom.






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






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






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






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






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






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






10. Energy in motion.






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






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






13. A method of obtaining energy from waste products






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






15. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






25. A resource that is entered into a system.






26. The capacity to do work or exert effort.






27. Creating things through the process of planning.






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






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






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






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






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






33. 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.






34. 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.






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






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






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






38. A popular movement.






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






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


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






42. 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.






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






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






45. Stored energy or energy at rest.






46. The formal rules that guide the design process.






47. Someone who starts a business.






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






49. 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.






50. 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.
