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. Creating things through the process of planning.






2. 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.






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






4. Someone who starts a business.






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






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






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






8. A method of obtaining energy from waste products






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






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






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






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






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

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






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






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






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






18. 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.






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






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






21. 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.






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






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






24. Restriction or limit placed on a product.






25. Stored energy or energy at rest.






26. The splitting of the nucleus of an atom.






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






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






29. Energy in motion.






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






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






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






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






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






35. 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.






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






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






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






39. The formal rules that guide the design process.






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






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






42. 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.






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






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






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






46. 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.'






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






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






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






50. 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.
