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






2. The splitting of the nucleus of an atom.






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






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






5. 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.






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






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






8. 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.






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






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






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






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






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






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






15. 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.






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






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






18. 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.






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






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






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






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






23. 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.






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






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






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






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






28. The formal rules that guide the design process.






29. The basic framework of a system






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






31. 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.






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






33. The capacity to do work or exert effort.






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






35. 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.






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






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 method of obtaining energy from waste products






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






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






41. Energy in motion.






42. Stored energy or energy at rest.






43. 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.'






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






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






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






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






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






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






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