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






2. Restriction or limit placed on a product.






3. 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.






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






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






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






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






8. 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.






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






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






11. The splitting of the nucleus of an atom.






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






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






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






15. The basic framework of a system






16. 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.






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






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






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






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






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






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






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






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






25. The capacity to do work or exert effort.






26. A method of obtaining energy from waste products






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






28. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






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






30. The capacity to do work or exert effort.






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






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






33. 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.






34. 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.






35. A popular movement.






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






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






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






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






40. Creating things through the process of planning.






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






42. 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.'






43. 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.






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






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






46. Stored energy or energy at rest.






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






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






49. 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.






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