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 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.






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






3. Someone who starts a business.






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






5. Restriction or limit placed on a product.






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






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






8. Stored energy or energy at rest.






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






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






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






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






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






14. 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.






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






16. 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.






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






18. 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.






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






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






21. 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.






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






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






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






25. A resource that is entered into a system.






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






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






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






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






30. 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.






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






32. 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.'






33. Energy in motion.






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






35. 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.






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






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






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






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






40. The splitting of the nucleus of an atom.






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






42. 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.






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






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






45. The capacity to do work or exert effort.






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






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






49. The capacity to do work or exert effort.






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