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






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






3. A method of obtaining energy from waste products






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






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






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

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






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






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






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






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






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






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






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






15. 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.






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






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






18. The capacity to do work or exert effort.






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






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






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






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






24. 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.






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






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






27. The splitting of the nucleus of an atom.






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






29. Restriction or limit placed on a product.






30. 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.






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. A popular movement.






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






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






35. Energy in motion.






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






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






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






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






40. The basic framework of a system






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






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






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






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






45. A resource that is entered into a system.






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






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






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






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






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