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






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






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






4. The capacity to do work or exert effort.






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






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






7. A method of obtaining energy from waste products






8. Restriction or limit placed on a product.






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






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






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






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






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






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






15. A resource that is entered into a system.






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






17. 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.






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






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






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






21. Creating things through the process of planning.






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






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






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






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






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






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






28. A popular movement.






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






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






31. 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.






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






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






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






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






36. 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.






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


38. Energy in motion.






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






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






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






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






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






44. Someone who starts a business.






45. The basic framework of a system






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






47. 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.






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






49. 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.






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