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






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






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






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






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






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






7. 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.'






8. The capacity to do work or exert effort.






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






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






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






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






13. 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.






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






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






16. 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.






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






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






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






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






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






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






23. Someone who starts a business.






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






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






26. A method of obtaining energy from waste products






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






28. A popular movement.






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






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






31. 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.






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






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






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






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






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






37. 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.






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






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






40. The act of breaking a particular subject into different parts to achieve clarity of understanding.






41. Energy in motion.






42. Stored energy or energy at rest.






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






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






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






46. The basic framework of a system






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






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






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






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