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 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.






2. A method of obtaining energy from waste products






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






4. Energy in motion.






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






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






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






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






9. 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.






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






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






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






13. A resource that is entered into a system.






14. Someone who starts a business.






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






16. The basic framework of a system






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






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 path by which electric current or pulses flow.






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






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






22. The splitting of the nucleus of an atom.






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






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






25. The capacity to do work or exert effort.






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






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


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






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






30. Creating things through the process of planning.






31. 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.






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






33. The formal rules that guide the design process.






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






35. 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.'






36. 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.






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






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






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






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






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






42. 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.






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






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






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






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






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






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






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






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