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. A tool for systematically ranking alternatives according to a set of criteria.






2. A truss composed of triangles - which will retain its shape even when removed from supports.






3. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

4. A straight line that comes closest to the points on a scatter plot






5. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






6. Test methods used to examine an object - material - or system without impairing its future usefulness






7. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






8. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






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






10. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






11. A surface or shape exposed by making a straight cut through something at right angles to the axis.






12. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






13. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






14. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






15. Frequency distibution graph






16. A gear positioned between the driver and the driven gear used to change rotational direction.






17. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






18. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






19. 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.

20. A result of a force moving an object a certain distance






21. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






22. Energy which a body possesses by virtue of being in motion






23. The information produced by a computer






24. The geometric center of an area.






25. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






26. A device used to convert fluid power into mechanical power in the form of linear motion.






27. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






28. The magnitude of the total distance traveled divided by the time elapsed.






29. The ratio of the magnitude of the resistance and effort forces applied a system.






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






31. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






32. The amount or quantity of something






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






34. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






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






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






37. The connection points of members of a truss






38. To monitor and control a process so that the quality of the output/product improves.






39. A tool for systematically ranking alternatives according to a set of criteria






40. The tank that holds the fluid in a hydraulic system.






41. A support that prevents translation in any direction






42. A group of machined or handmade parts that fit together to form a self- contained unit.






43. A subset of a sample space






44. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






45. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

46. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






47. The production of electricity in conductors with the use of magnets






48. The square root of the variance.






49. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






50. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic
