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






2. Restriction or limit placed on a product.






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






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






5. Creating things through the process of planning.






6. 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.






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






8. The use of 3D CAD drawings to create real models of a product within a sort of time.






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






10. 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.






11. Stored energy or energy at rest.






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






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 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 judgement of the end result based upon given criteria.






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






17. 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.






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






19. 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.






20. The formal rules that guide the design process.






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






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


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






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






25. The capacity to do work or exert effort.






26. 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.






27. 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.






28. A popular movement.






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






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






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






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






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






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






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






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






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






40. Energy in motion.






41. A method of obtaining energy from waste products






42. The capacity to do work or exert effort.






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






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






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






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






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






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






49. 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.






50. The splitting of the nucleus of an atom.
