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






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






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






4. The formal rules that guide the design process.






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






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






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






8. The capacity to do work or exert effort.






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






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






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






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






13. A popular movement.






14. 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.






15. A resource that is entered into a system.






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






17. Someone who starts a business.






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






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






20. 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.






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






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






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






24. 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.






25. Creating things through the process of planning.






26. 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.






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






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






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






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






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






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






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






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






35. 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.






36. 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.






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






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






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






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






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






42. Energy in motion.






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






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






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






46. A method of obtaining energy from waste products






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






48. 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.






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






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