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






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






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






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






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






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






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






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






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






10. 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.






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






12. 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.






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






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






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






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






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






18. Creating things through the process of planning.






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






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






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






22. The basic framework of a system






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






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






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


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






27. The capacity to do work or exert effort.






28. The splitting of the nucleus of an atom.






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






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






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






32. A method of obtaining energy from waste products






33. 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.






34. Someone who starts a business.






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






36. 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.






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






38. Stored energy or energy at rest.






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






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






41. A resource that is entered into a system.






42. 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.






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






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






45. 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.






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






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






48. The formal rules that guide the design process.






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






50. A popular movement.
