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






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






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






5. 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.






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






7. 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.






8. Energy in motion.






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






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






11. A method of obtaining energy from waste products






12. The capacity to do work or exert effort.






13. 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.






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






15. 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.






16. Restriction or limit placed on a product.






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






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






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






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






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






22. A resource that is entered into a system.






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






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






25. 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.






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






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






28. 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.






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






30. The splitting of the nucleus of an atom.






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






32. A popular movement.






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






34. The capacity to do work or exert effort.






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






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






37. 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.






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






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






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






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






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






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






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






45. Stored energy or energy at rest.






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






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






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






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






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