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






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






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






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






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






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






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






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






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






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






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






12. 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.'






13. Stored energy or energy at rest.






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






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






16. Someone who starts a business.






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






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






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






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






21. The capacity to do work or exert effort.






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






24. The formal rules that guide the design process.






25. 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.






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






27. 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.






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






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






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






31. Energy in motion.






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






33. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






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






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






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






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 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.






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






40. 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.






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


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






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






44. 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.






45. A method of obtaining energy from waste products






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






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






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






49. A resource that is entered into a system.






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