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






2. The capacity to do work or exert effort.






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


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






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






6. Stored energy or energy at rest.






7. 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.






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






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






10. A resource that is entered into a system.






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






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






13. 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.






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






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






16. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






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






18. The formal rules that guide the design process.






19. A method of obtaining energy from waste products






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






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






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






23. A popular movement.






24. 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.'






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






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






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






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






29. Someone who starts a business.






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






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






32. 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.






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






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






35. The unlawful acquisition of some one's personal information for use without their consent.






36. 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.






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






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






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






40. 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.






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






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






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






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






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






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






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






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






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






50. Creating things through the process of planning.
