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. 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.






2. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






3. Frequency distibution graph






4. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






5. Degree of conformity of a measure to a standard value.






6. A written plan that identifies a problem to be solved - its criteria - and its constraints.






7. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






8. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






9. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






10. 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.






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






12. 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






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






14. The value that occurs most frequently






15. A systemized body of laws; a set of principles - as of ethics






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






17. The use of gas flowing under pressure to transmit power from one location to another.






18. Conversion of a digital signal to its analog equivalent - such as a voltage.






19. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






20. Individual fuel cells that are combined in series.






21. 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.






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






23. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






24. The stress required to fracture a material whether by compression - tension - or shear






25. Middle value of a set of values arranged in order of magnitude.






26. A general agreement






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






28. A subset of a sample space






29. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






30. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






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






32. The process of creating an object by adding small pieces or layers together to make a final product






33. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






34. A device used to create flow in a hydraulic system.






35. The amount or quantity of something






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






37. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






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






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






40. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






41. A sketch that shows an object's height - width - and depth in a single view.






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






43. Energy caused by the movement of electrons.






44. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






45. A device that holds the compressed air in a pneumatic system.






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






47. A part of the physical world as described by its thermodynamic properties such as temperature - volume - pressure - concentration - surface tension - and viscosity.






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






49. 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






50. A switch that can provide variable motion control
