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






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






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






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






5. 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.






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






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






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






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






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






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






12. Creating things through the process of planning.






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






14. The capacity to do work or exert effort.






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






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






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






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






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






20. Energy in motion.






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






22. 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.






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






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






25. The splitting of the nucleus of an atom.






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






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






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






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






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






31. Restriction or limit placed on a product.






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






33. The formal rules that guide the design process.






34. 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.






35. 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.






36. 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.'






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






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


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






40. A resource that is entered into a system.






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






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






43. Stored energy or energy at rest.






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






45. 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.






46. A popular movement.






47. 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.






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






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






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