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






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






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






4. Creating things through the process of planning.






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






6. 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.






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






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






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






10. The capacity to do work or exert effort.






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






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






13. The basic framework of a system






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






15. The splitting of the nucleus of an atom.






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






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






18. A method of obtaining energy from waste products






19. 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.






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






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






22. Someone who starts a business.






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






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


25. Energy in motion.






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






27. Restriction or limit placed on a product.






28. 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.






29. 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.






30. Stored energy or energy at rest.






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






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






33. A popular movement.






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






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






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






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






38. 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.'






39. The formal rules that guide the design process.






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






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






42. 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.






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






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






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






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






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






48. 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.






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






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