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






3. Restriction or limit placed on a product.






4. 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.'






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






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






7. 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.






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






9. 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.






10. The formal rules that guide the design process.






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. Stored energy or energy at rest.






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






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






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






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






17. 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.






18. 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.






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






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






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






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






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






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






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






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






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






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






31. The splitting of the nucleus of an atom.






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






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






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






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






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






37. Creating things through the process of planning.






38. The capacity to do work or exert effort.






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






40. 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.






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






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






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






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






45. 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.






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






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






48. A resource that is entered into a system.






49. Energy in motion.






50. A popular movement.
