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






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






4. The splitting of the nucleus of an atom.






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






6. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






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






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






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






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






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






12. The formal rules that guide the design process.






13. 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.






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






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


16. A popular movement.






17. 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.






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






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






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






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






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






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






24. 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.'






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






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






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






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






29. The capacity to do work or exert effort.






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






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






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






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






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






35. The capacity to do work or exert effort.






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






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






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






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






41. 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.






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






43. A method of obtaining energy from waste products






44. 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.






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






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






47. Someone who starts a business.






48. A resource that is entered into a system.






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






50. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.
