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






3. 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.






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






5. The formal rules that guide the design process.






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






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






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


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






10. 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.






11. 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.






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






13. 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.'






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






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






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






17. A popular movement.






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






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






20. A resource that is entered into a system.






21. 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.






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






23. 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.






24. Creating things through the process of planning.






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






26. Someone who starts a business.






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






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






29. A method of obtaining energy from waste products






30. The basic framework of a system






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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 use of computers in each stage of the design process.






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






50. 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.
