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 superimposition of sine waves on electromagnetic carrier waves.






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






3. The splitting of the nucleus of an atom.






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






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






6. 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.






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






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






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






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






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






12. Creating things through the process of planning.






13. Stored energy or energy at rest.






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






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






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






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






18. The basic framework of a system






19. A popular movement.






20. 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.






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






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






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






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






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






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






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






28. The formal rules that guide the design process.






29. The capacity to do work or exert effort.






30. Restriction or limit placed on a product.






31. Energy in motion.






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






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






34. 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.






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






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






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






39. 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.






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






41. 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.






42. 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.






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






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






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






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






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






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






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






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