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 splitting of the nucleus of an atom.






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






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






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






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






6. 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.'






7. Restriction or limit placed on a product.






8. The capacity to do work or exert effort.






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






10. 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.






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






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






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






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






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






16. 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.






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






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






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






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






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






22. 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.






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






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






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






26. 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.






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






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






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






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






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






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






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






34. A method of obtaining energy from waste products






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






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






37. The basic framework of a system






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


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






40. 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.






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






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






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






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






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






46. 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.






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






48. 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.






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






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