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 judgement of the end result based upon given criteria.






2. Energy in motion.






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






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






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






6. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






7. 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.






8. 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.






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






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






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






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






13. 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.






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






15. A method of obtaining energy from waste products






16. 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.






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






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






19. 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.'






20. The capacity to do work or exert effort.






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






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






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






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


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






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






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






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






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






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






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






32. Restriction or limit placed on a product.






33. Someone who starts a business.






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






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






37. The capacity to do work or exert effort.






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






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






40. 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.






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






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






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






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






45. The splitting of the nucleus of an atom.






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






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






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






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






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