Technical Design And Engineering

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. Stored energy or energy at rest.






2. The capacity to do work or exert effort.






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






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






5. 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.






6. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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






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






17. Someone who starts a business.






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






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






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






21. 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.






22. 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.






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






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






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






26. 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.






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






28. 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.






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






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






31. A resource that is entered into a system.






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






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






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






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






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






37. Energy in motion.






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






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






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






41. 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.'






42. A popular movement.






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






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






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






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






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






48. 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.






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






50. The formal rules that guide the design process.
