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. Creating things through the process of planning.






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






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






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






6. The capacity to do work or exert effort.






7. 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.






8. 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.






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






10. Restriction or limit placed on a product.






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






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






13. 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.






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






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






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






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






18. A resource that is entered into a system.






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






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






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






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






23. Stored energy or energy at rest.






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






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






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






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






28. The formal rules that guide the design process.






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






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






31. 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.






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






33. The capacity to do work or exert effort.






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






35. 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.






36. Someone who starts a business.






37. A popular movement.






38. The splitting of the nucleus of an atom.






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






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






41. A method of obtaining energy from waste products






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






43. 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.






44. The basic framework of a system






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






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


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






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






49. 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.






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