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 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.






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






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






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






5. 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.






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






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






8. 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.






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






10. 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.






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


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






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






14. 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.






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






16. 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.






17. The use of force to act on an object in order to move move the object in the same direction as the force.






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






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






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






21. A method of obtaining energy from waste products






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






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






24. A popular movement.






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






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






27. The basic framework of a system






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






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






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






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






33. 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.'






34. Someone who starts a business.






35. Energy in motion.






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






37. Creating things through the process of planning.






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






39. The capacity to do work or exert effort.






40. A resource that is entered into a system.






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






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






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






44. 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.






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






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






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






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






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






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