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 circuit in which electricity flows along more than one path.






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






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






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






5. 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.






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






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






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






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






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






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






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






13. Someone who starts a business.






14. 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.






15. 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.'






16. The capacity to do work or exert effort.






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






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






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






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






21. The splitting of the nucleus of an atom.






22. 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.






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






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






26. Energy in motion.






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






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






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






30. The capacity to do work or exert effort.






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






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






33. 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.






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






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






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






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






38. Restriction or limit placed on a product.






39. 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.






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






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


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






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






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






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






46. Stored energy or energy at rest.






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






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






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






50. Creating things through the process of planning.
