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






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






3. 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.






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






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






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






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






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






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






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






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






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






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






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






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






16. A resource that is entered into a system.






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






18. 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.






19. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






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






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






22. 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.






23. A popular movement.






24. The capacity to do work or exert effort.






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






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






27. 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.






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






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






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






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






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






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






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






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






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






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






38. The splitting of the nucleus of an atom.






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






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






41. A method of obtaining energy from waste products






42. Someone who starts a business.






43. The capacity to do work or exert effort.






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






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






46. Stored energy or energy at rest.






47. 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.






48. Restriction or limit placed on a product.






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






50. The basic framework of a system
