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. Restriction or limit placed on a product.






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






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






4. A popular movement.






5. 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.






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






7. Stored energy or energy at rest.






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






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






10. 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.






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






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






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






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






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






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






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






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






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






21. 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.






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






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






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






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






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






27. A method of obtaining energy from waste products






28. The capacity to do work or exert effort.






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






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






31. The formal rules that guide the design process.






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






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






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






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






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






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






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






40. 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.'






41. 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.






42. 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.






43. The basic framework of a system






44. 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.






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






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






47. 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.






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


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






50. Energy in motion.
