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






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






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






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






5. 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.






6. A method of obtaining energy from waste products






7. The splitting of the nucleus of an atom.






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






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






10. 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.'






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






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






13. A popular movement.






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






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

16. The basic framework of a system






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






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






19. 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.






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






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






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






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






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






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






27. Someone who starts a business.






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






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






30. 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.






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






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






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






34. 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.






35. Energy in motion.






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






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






38. 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.






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






40. 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.






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






42. 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.






43. A resource that is entered into a system.






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






45. 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.






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






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






48. The capacity to do work or exert effort.






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






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