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 capacity to do work or exert effort.






2. 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.






3. 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.






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






5. The capacity to do work or exert effort.






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






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






8. A resource that is entered into a system.






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






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






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






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






13. A popular movement.






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






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






16. 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.






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






18. 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.'






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






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






21. 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.






22. 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.






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






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






25. A method of obtaining energy from waste products






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






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






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






30. The splitting of the nucleus of an atom.






31. Restriction or limit placed on a product.






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






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






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






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






36. 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.






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






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






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






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






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






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






43. Someone who starts a business.






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






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






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






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






48. 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.






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






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