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






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






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






4. A method of obtaining energy from waste products






5. The splitting of the nucleus of an atom.






6. 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.






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






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






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






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






11. Someone who starts a business.






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






13. The capacity to do work or exert effort.






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






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






16. Stored energy or energy at rest.






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






18. 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.






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






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






21. The formal rules that guide the design process.






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






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






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






25. Creating things through the process of planning.






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






27. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






37. 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.






38. 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.






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






40. The act of putting different things together to form a new product or idea.






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






42. 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.'






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






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






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






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






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






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






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






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