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 path by which electric current or pulses flow.






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






3. 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.






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






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






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






7. 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.






8. A method of obtaining energy from waste products






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






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






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






12. Someone who starts a business.






13. Restriction or limit placed on a product.






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






15. A resource that is entered into a system.






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






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






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






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






20. 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.






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






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






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






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






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






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






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






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






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






30. 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.'






31. 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.






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






33. The formal rules that guide the design process.






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






35. Stored energy or energy at rest.






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






37. The splitting of the nucleus of an atom.






38. Creating things through the process of planning.






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






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






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






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






43. Energy in motion.






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






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






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






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






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






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






50. 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.
