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 superimposition of sine waves on electromagnetic carrier waves.






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






3. Restriction or limit placed on a product.






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






5. The formal rules that guide the design process.






6. 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.






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






8. The unlawful acquisition of some one's personal information for use without their consent.






9. 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.'






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






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






12. The basic framework of a system






13. Someone who starts a business.






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






15. A popular movement.






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






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






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






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






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






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






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






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






24. Energy in motion.






25. 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.






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






27. 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.






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


30. A method of obtaining energy from waste products






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






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






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






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






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






36. 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.






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






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






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






40. 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.






41. Creating things through the process of planning.






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






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






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






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






46. The splitting of the nucleus of an atom.






47. Stored energy or energy at rest.






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






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






50. 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.
