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






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






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






4. 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.






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






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






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






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






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






10. The capacity to do work or exert effort.






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






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






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






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






15. A popular movement.






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






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






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






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






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






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






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






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






24. 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.






25. Stored energy or energy at rest.






26. Creating things through the process of planning.






27. 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.






28. The basic framework of a system






29. The splitting of the nucleus of an atom.






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






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






32. 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.






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






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






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






37. Restriction or limit placed on a product.






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






39. 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.






40. The capacity to do work or exert effort.






41. Energy in motion.






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. Someone who starts a business.






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






45. The formal rules that guide the design process.






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






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






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






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






50. A method of obtaining energy from waste products
