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.

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






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






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






10. 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.






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






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






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






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






15. A popular movement.






16. A resource that is entered into a system.






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






18. 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.'






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






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






21. The use of computers in each stage of the design process.






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






23. The splitting of the nucleus of an atom.






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






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






26. Energy in motion.






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






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






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






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






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






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






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






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






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






36. 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.






37. A method of obtaining energy from waste products






38. 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.






39. Creating things through the process of planning.






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






41. 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.






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






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






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






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






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






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






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






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