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 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.






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






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






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






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






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






7. The splitting of the nucleus of an atom.






8. Someone who starts a business.






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






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






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






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






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






14. Stored energy or energy at rest.






15. The basic framework of a system






16. A resource that is entered into a system.






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






18. 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.






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






20. 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.'






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






22. A method of obtaining energy from waste products






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






24. 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.






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






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






27. Creating things through the process of planning.






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






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






30. 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.






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






32. The capacity to do work or exert effort.






33. 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.






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






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






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






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






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


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






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






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






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






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






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






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






46. The capacity to do work or exert effort.






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






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






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






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