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 lasers to record realistic images of three- dimensional objects.






2. The capacity to do work or exert effort.






3. A method of obtaining energy from waste products






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






5. Creating things through the process of planning.






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






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






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






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






10. 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.






11. Restriction or limit placed on a product.






12. 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.






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






14. The formal rules that guide the design process.






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






16. 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.






17. 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.






18. A popular movement.






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






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






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






22. Stored energy or energy at rest.






23. 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.






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






25. 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.






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






27. The basic framework of a system






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






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






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






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






32. The splitting of the nucleus of an atom.






33. 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.






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






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






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






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






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






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






40. 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.'






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






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






43. 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.






44. 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.






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






46. A resource that is entered into a system.






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






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


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






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