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. 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.






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






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






5. 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.'






6. 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.






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






8. 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.






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






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






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






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






14. The capacity to do work or exert effort.






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






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






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






18. A method of obtaining energy from waste products






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






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






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






22. Someone who starts a business.






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






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






25. Restriction or limit placed on a product.






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






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






28. Stored energy or energy at rest.






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






30. 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.






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






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






33. The capacity to do work or exert effort.






34. The formal rules that guide the design process.






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






36. 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.






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






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






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. 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.






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






42. The unlawful acquisition of some one's personal information for use without their consent.






43. 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.






44. Energy in motion.






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






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






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






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






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






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