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. Someone who starts a business.






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






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






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






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






6. 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.






7. 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.






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






9. The formal rules that guide the design process.






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






11. Stored energy or energy at rest.






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






13. 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.






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






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






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






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






18. A group of people working together to accomplish a common goal.






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






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






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






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






23. The basic framework of a system






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






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






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






28. 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.






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






30. 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.'






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






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






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






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






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






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






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






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






39. A method of obtaining energy from waste products






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






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






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






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






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






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






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






47. 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.






48. A resource that is entered into a system.






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






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