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 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.






2. The capacity to do work or exert effort.






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






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






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






6. The capacity to do work or exert effort.






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






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






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






10. Stored energy or energy at rest.






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






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






14. 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.






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






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






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






18. A popular movement.






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






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






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






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






23. 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.






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






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






26. 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.'






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






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






29. The formal rules that guide the design process.






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






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






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






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






34. Creating things through the process of planning.






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






36. 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.






37. The basic framework of a system






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






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






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






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






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






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






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






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






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


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 splitting of the nucleus of an atom.






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






50. A resource that is entered into a system.
