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 money a business makes after all expenses have been paid






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






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






4. Energy in motion.






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






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






7. A method of obtaining energy from waste products






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






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






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






11. 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.






12. Someone who starts a business.






13. The basic framework of a system






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






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






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






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






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






19. 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.






20. 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.






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






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






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






24. 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.






25. Stored energy or energy at rest.






26. 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.






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






28. The act of breaking a particular subject into different parts to achieve clarity of understanding.






29. A popular movement.






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






31. The splitting of the nucleus of an atom.






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






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






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


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






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






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






38. 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.






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






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






41. 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.






42. The formal rules that guide the design process.






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






44. 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.'






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






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






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






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






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






50. The capacity to do work or exert effort.
