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 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.






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






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






4. 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.






5. 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.






6. Someone who starts a business.






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






8. The basic framework of a system






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






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






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






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






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






14. Restriction or limit placed on a product.






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






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






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






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






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






20. Stored energy or energy at rest.






21. The capacity to do work or exert effort.






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






23. A method of obtaining energy from waste products






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






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






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






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






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






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






30. 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.






31. A popular movement.






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






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






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






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






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






37. 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.






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






39. The splitting of the nucleus of an atom.






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






41. Creating things through the process of planning.






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






43. 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.






44. Energy in motion.






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. 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.






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






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






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






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