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






2. 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.






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






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






5. 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.






6. The splitting of the nucleus of an atom.






7. Restriction or limit placed on a product.






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






9. The capacity to do work or exert effort.






10. A resource that is entered into a system.






11. 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.'






12. 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.






13. Creating things through the process of planning.






14. Energy in motion.






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






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






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






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






19. 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.






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






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






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






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






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






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






26. A popular movement.






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






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






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






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






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. 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.






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






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






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






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






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






38. 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.






39. 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.






40. Someone who starts a business.






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 formal rules that guide the design process.






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






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






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






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






47. The basic framework of a system






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






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






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