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






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






3. The formal rules that guide the design process.






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






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






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






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






8. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






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






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






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






12. A resource that is entered into a system.






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






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






15. Stored energy or energy at rest.






16. 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.'






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






18. A popular movement.






19. The capacity to do work or exert effort.






20. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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 money a business makes after all expenses have been paid






30. A method of obtaining energy from waste products






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






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






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






34. 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.






35. 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.






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






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






38. The basic framework of a system






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






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






41. The capacity to do work or exert effort.






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






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






45. 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.






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






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






48. Energy in motion.






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






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