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 basic framework of a system






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






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






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






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






6. Stored energy or energy at rest.






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






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






9. Someone who starts a business.






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






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






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






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






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






16. 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.






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






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






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






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






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






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






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






24. 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.






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






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






27. 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.






28. 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.






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






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


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






32. 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.






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






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






35. The formal rules that guide the design process.






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






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






38. 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.






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






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






41. A resource that is entered into a system.






42. A method of obtaining energy from waste products






43. A popular movement.






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






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






46. 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.






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






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






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. 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.
