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. 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.






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






4. The capacity to do work or exert effort.






5. 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.






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






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






8. 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.






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






10. Stored energy or energy at rest.






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






12. 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.






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






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






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






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






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






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






19. Restriction or limit placed on a product.






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






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


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






23. The capacity to do work or exert effort.






24. 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.






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






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






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






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






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






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






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






32. Creating things through the process of planning.






33. Energy in motion.






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






35. The splitting of the nucleus of an atom.






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






37. 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.






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






40. A resource that is entered into a system.






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






42. 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.'






43. 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.






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






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






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






47. The basic framework of a system






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






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






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