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






2. 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.






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






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






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






6. A resource that is entered into a system.






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






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






9. 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.






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






11. A method of obtaining energy from waste products






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






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






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






15. 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.






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






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






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






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






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






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






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






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






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






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






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






27. Energy in motion.






28. 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.






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






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






31. 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.






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






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






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






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






36. The capacity to do work or exert effort.






37. 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.






38. Stored energy or energy at rest.






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






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






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






42. Restriction or limit placed on a product.






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






44. 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.'






45. The capacity to do work or exert effort.






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






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






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






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






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