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






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






3. The capacity to do work or exert effort.






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






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






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






7. 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.






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






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






10. A method of obtaining energy from waste products






11. The basic framework of a system






12. 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.






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






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






15. 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.






16. Restriction or limit placed on a product.






17. 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.






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. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






29. The splitting of the nucleus of an atom.






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






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






32. 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.






33. A resource that is entered into a system.






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






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






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






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






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






39. 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.'






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






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






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






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






44. The formal rules that guide the design process.






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






46. Stored energy or energy at rest.






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






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 group of people working together to accomplish a common goal.






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