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






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






3. 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.






4. 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.






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






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






7. Creating things through the process of planning.






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






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






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






11. A method of obtaining energy from waste products






12. 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.






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






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






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






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






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






18. Stored energy or energy at rest.






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






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






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






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


23. The splitting of the nucleus of an atom.






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






25. 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.






26. A popular movement.






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






28. 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.






29. 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.






30. Energy in motion.






31. 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.'






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






33. The basic framework of a system






34. 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.






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






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






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






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






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






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






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






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






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






44. A resource that is entered into a system.






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






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






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






48. The capacity to do work or exert effort.






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






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