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






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






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






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






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






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






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






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






9. 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.






10. 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.






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






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






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






14. The basic framework of a system






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






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






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






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


19. Creating things through the process of planning.






20. 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.






21. 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.






22. The capacity to do work or exert effort.






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






24. Someone who starts a business.






25. 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.






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






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






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






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






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






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






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






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






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






35. 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.






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






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






38. Restriction or limit placed on a product.






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






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






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






42. 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.






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






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






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






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






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






48. Stored energy or energy at rest.






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






50. Energy in motion.
