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. 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.






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






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






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






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






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






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






8. Creating things through the process of planning.






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






10. The basic framework of a system






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






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






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






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






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






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






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






18. A popular movement.






19. A method of obtaining energy from waste products






20. Stored energy or energy at rest.






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






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






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






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






25. The formal rules that guide the design process.






26. A resource that is entered into a system.






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






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






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






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






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






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






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






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






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






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






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






39. 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.






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






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






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






43. 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.'






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






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






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






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






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






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






50. 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.
