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 computers in each stage of the design process.






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






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






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






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






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






7. The formal rules that guide the design process.






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






9. 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.'






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






11. A popular movement.






12. 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.






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. Restriction or limit placed on a product.






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






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






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






18. Someone who starts a business.






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






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






21. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






22. The capacity to do work or exert effort.






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






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






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






26. Creating things through the process of planning.






27. A resource that is entered into a system.






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






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






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






31. 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.






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






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






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






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






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






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






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






39. 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.






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






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






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


43. 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.






44. The splitting of the nucleus of an atom.






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






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






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






48. Energy in motion.






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






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