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 capacity to do work or exert effort.






2. 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.






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






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






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 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. Stored energy or energy at rest.






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






10. 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.






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






12. A popular movement.






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






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






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






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






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






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






19. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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






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






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






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






32. 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.






33. 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.






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






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






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






37. The splitting of the nucleus of an atom.






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






39. Energy in motion.






40. Creating things through the process of planning.






41. 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.






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


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






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






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






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






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






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






49. Restriction or limit placed on a product.






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