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






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






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






4. Creating things through the process of planning.






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






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






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






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






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






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






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






12. Stored energy or energy at rest.






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






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






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






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






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


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






19. Energy in motion.






20. 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.






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






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






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






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






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






26. 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.






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






28. 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.






29. The capacity to do work or exert effort.






30. The capacity to do work or exert effort.






31. A popular movement.






32. 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.






33. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






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. 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.






36. The splitting of the nucleus of an atom.






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






38. Restriction or limit placed on a product.






39. Someone who starts a business.






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






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






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






43. 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.






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






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






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






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






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