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






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






3. 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.






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






5. 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.






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






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






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






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






10. 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.






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






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






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






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






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






16. 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.






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






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






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






20. Energy in motion.






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






22. 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.'






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






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






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






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






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






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






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






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






31. A method of obtaining energy from waste products






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






33. 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.






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






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






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






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






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






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






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






41. A resource that is entered into a system.






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






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






44. Stored energy or energy at rest.






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






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






47. The capacity to do work or exert effort.






48. Restriction or limit placed on a product.






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






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