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






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






3. The capacity to do work or exert effort.






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






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






6. 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.






7. 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.






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






9. Standards that a product must meet to be accepted.






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






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






12. Creating things through the process of planning.






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






14. 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.






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






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






17. A resource that is entered into a system.






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






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






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






21. The formal rules that guide the design process.






22. 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.






23. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






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






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






35. The splitting of the nucleus of an atom.






36. 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.






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






38. Stored energy or energy at rest.






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






40. 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.






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






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






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






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






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






46. A popular movement.






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






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






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






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