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. Someone who starts a business.






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






3. 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.






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






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






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






7. 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.






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






9. The formal rules that guide the design process.






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


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






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






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






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






15. 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.'






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






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






18. A popular movement.






19. The capacity to do work or exert effort.






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






21. 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.






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






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






24. A resource that is entered into a system.






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






26. A method of obtaining energy from waste products






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






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






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






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






31. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






32. The splitting of the nucleus of an atom.






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






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






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






37. 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.






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






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






40. Energy in motion.






41. 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.






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






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






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






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






46. 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.






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






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






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






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