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






2. The capacity to do work or exert effort.






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






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


5. 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.






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






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






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






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






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






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






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






13. 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.






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






15. A method of obtaining energy from waste products






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






17. Creating things through the process of planning.






18. Someone who starts a business.






19. 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.






20. The splitting of the nucleus of an atom.






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






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






23. 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.






24. Restriction or limit placed on a product.






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






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






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






28. 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.'






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






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






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






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






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






34. 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.






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






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






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






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






39. 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.






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






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






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






44. Energy in motion.






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






46. A popular movement.






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






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






49. 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.






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