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 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.






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






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






4. Stored energy or energy at rest.






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






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






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






8. A resource that is entered into a system.






9. 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.






10. The formal rules that guide the design process.






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


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






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






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






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






16. A popular movement.






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






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






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






20. 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.






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






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






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






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






25. The judgement of the end result based upon given criteria.






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






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






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






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






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






31. The capacity to do work or exert effort.






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






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






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






35. 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.






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






37. 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.






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






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






40. 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.






41. 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.






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






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






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






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






46. The capacity to do work or exert effort.






47. A method of obtaining energy from waste products






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






49. The splitting of the nucleus of an atom.






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