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






2. 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.






3. 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.






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






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






6. 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.






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






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






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






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






11. 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.






12. A method of obtaining energy from waste products






13. The splitting of the nucleus of an atom.






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






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






17. 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.






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






19. Restriction or limit placed on a product.






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






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






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






23. A popular movement.






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






25. Energy in motion.






26. The capacity to do work or exert effort.






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






28. 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.






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






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






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






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






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






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






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






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






37. A resource that is entered into a system.






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






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






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


41. Creating things through the process of planning.






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






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






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






45. The basic framework of a system






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






47. Someone who starts a business.






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






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






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