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






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






3. 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.






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






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






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






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






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






9. The basic framework of a system






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






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






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






13. 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.






14. 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.






15. 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.






16. The capacity to do work or exert effort.






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






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






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






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






21. 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.






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






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






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






25. The capacity to do work or exert effort.






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






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


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






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






30. Creating things through the process of planning.






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






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






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






34. Energy in motion.






35. The splitting of the nucleus of an atom.






36. 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.






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






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






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






40. 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.






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






42. The formal rules that guide the design process.






43. 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.






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






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






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






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






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






49. A popular movement.






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