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






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






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






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






5. 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.






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






7. A method of obtaining energy from waste products






8. 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.






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






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






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






12. Creating things through the process of planning.






13. The basic framework of a system






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






15. Restriction or limit placed on a product.






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






17. The capacity to do work or exert effort.






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






19. 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.






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

21. The splitting of the nucleus of an atom.






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






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






24. 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.






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






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






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






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






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






30. 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.






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






32. 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.'






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






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






35. 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.






36. The capacity to do work or exert effort.






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






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






39. 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.






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






41. Energy in motion.






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






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






44. Someone who starts a business.






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






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






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






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






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






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