Principles Of 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. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






2. A device for making - breaking - or changing the connections in an electrical circuit.






3. Two different sized circular objects that are attached together and turn as one.






4. Bell- shaped probability distribution






5. A measure of a fluid's thickness or resistance to flow.






6. A switching device that uses the magnetic field generated by an electrical current for actuation.






7. An external force applied to an object.






8. Plant materials and animal waste used especially as a source of fuel.






9. The collection - evaluation - and interpretation of data






10. The contact of a relay that is open when the coil is de- energized






11. A device used to measure flow rate.






12. A support that prevents translation and rotation in a beam.






13. The difference between the maximum and minimum dimensions allowed within the design of a product.






14. Categorical data graph






15. A force that produces or tends to produce rotation or torsion.






16. An air pump that compresses air into a receiver tank.






17. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






18. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






19. Impeding effect exerted by one material object on another.






20. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






21. An electromagnetically operated switching device.






22. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






23. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

24. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






25. The use of a liquid flowing under pressure to transmit power from one location to another






26. Categorical data graph percentage






27. Used to start and stop flow in a circuit






28. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






29. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






30. The distance the fluid travels through a system in a given period of time.






31. An energy source that will never run out






32. A general agreement






33. The rate at which work is performed or energy is expended






34. A valve that allows flow in one direction but prevents flow in the opposite direction.






35. Energy caused by the movement of electrons.






36. A person or group for which product or service design efforts are intended.






37. The value that occurs most frequently






38. Used to control which path fluid takes in a circuit.






39. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






40. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






41. The transfer of energy by electromagnetic waves






42. Conversion of an analog signal to a digital quantity such as binary.






43. A control system that considers the output of a system and makes adjustments based on that output.






44. A body subjected to a push.






45. The flow of electrical power or charge.






46. The force per unit area exerted by a fluid against a surface






47. The condition or quality of being true - correct - or exact; precision; exactness.






48. A vector quantity that includes the speed and direction of an object.






49. The fractional increase in a material's length due to stress in tension or thermal expansion






50. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat
