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. Energy in motion.






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






4. The formal rules that guide the design process.






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






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






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






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






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






10. Creating things through the process of planning.






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






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






13. The capacity to do work or exert effort.






14. The basic framework of a system






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






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






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






19. 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.'






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






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






22. 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.






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






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






25. 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.






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






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






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






29. 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.






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






31. The capacity to do work or exert effort.






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






33. The splitting of the nucleus of an atom.






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






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. A method of obtaining energy from waste products






37. 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.






38. 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.






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






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






41. 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.






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






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






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






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






46. A resource that is entered into a system.






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






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


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






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