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






2. The splitting of the nucleus of an atom.






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






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






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


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






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






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






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






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






11. A popular movement.






12. 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.






13. The basic framework of a system






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






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






16. 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.






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






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






19. The capacity to do work or exert effort.






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






21. The capacity to do work or exert effort.






22. Restriction or limit placed on a product.






23. 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.






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






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






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






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






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






29. 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.






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






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






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






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






36. Someone who starts a business.






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






38. 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.






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






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






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






42. 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.






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






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






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






46. 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.






47. Creating things through the process of planning.






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






49. 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.'






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