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






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






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






4. The basic framework of a system






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






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






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






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






9. Energy in motion.






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






11. Restriction or limit placed on a product.






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






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






14. 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.






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






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






17. The splitting of the nucleus of an atom.






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






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






20. Creating things through the process of planning.






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






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






23. 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.






24. 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.






25. The formal rules that guide the design process.






26. Current flow in which electrons reverse direction at regular intervals.






27. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






36. Someone who starts a business.






37. 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.






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






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






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






41. The capacity to do work or exert effort.






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


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






44. A popular movement.






45. 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.






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






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






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






49. 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.'






50. A resource that is entered into a system.
