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






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






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






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






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






6. The formal rules that guide the design process.






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






8. A method of obtaining energy from waste products






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






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






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






12. 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.






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






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






15. The capacity to do work or exert effort.






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






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






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






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






20. 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.






21. 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.'






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






23. 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.






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


25. 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.






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






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






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






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






30. Energy in motion.






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






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






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






34. Creating things through the process of planning.






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






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






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






38. The splitting of the nucleus of an atom.






39. A popular movement.






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






41. Someone who starts a business.






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






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






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






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






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






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






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






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






50. The capacity to do work or exert effort.
