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






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






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






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






5. Energy in motion.






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






7. 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.






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

9. 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.






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. 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.






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






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






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






15. Someone who starts a business.






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






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






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






19. The basic framework of a system






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






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






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






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






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






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






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






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






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






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






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






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






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






34. 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.






35. A popular movement.






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






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






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






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






40. The formal rules that guide the design process.






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






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






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






44. 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.






45. 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.'






46. 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.






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






48. The capacity to do work or exert effort.






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






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