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






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






3. Energy in motion.






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






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






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






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






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






10. Stored energy or energy at rest.






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






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






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






14. Someone who starts a business.






15. Creating things through the process of planning.






16. Restriction or limit placed on a product.






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






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






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






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






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






23. 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.'






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






25. A method of obtaining energy from waste products






26. 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.






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






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






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






30. 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.






31. 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.






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






33. A popular movement.






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






35. The splitting of the nucleus of an atom.






36. 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.






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






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






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






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






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






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






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






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






45. A resource that is entered into a system.






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






47. 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.






48. The capacity to do work or exert effort.






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






50. The basic framework of a system
