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






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






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






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






5. The capacity to do work or exert effort.






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






7. Creating things through the process of planning.






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






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






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






11. The basic framework of a system






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






13. 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.






14. 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.'






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






16. The capacity to do work or exert effort.






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






18. 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.






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






20. 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.






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






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






23. Restriction or limit placed on a product.






24. A popular movement.






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






26. 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.






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






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






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






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






31. 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.






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






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






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






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






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






37. 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.






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






39. The formal rules that guide the design process.






40. Stored energy or energy at rest.






41. 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.






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






43. A method of obtaining energy from waste products






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






45. Someone who starts a business.






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


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






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






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






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