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. 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.






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






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






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






5. 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.






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






7. The splitting of the nucleus of an atom.






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






9. The capacity to do work or exert effort.






10. Energy in motion.






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






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






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






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






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






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






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






18. Restriction or limit placed on a product.






19. Someone who starts a business.






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






21. A method of obtaining energy from waste products






22. Creating things through the process of planning.






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






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






25. 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.






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






27. 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.'






28. The basic framework of a system






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






30. 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.






31. Stored energy or energy at rest.






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






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






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 popular movement.






36. 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.






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


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






39. 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.






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






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






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






43. A resource that is entered into a system.






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






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






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






47. The formal rules that guide the design process.






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






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






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