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. Impeding effect exerted by one material object on another.






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






3. Changes one form of power to another






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






5. The total pressure exerted on a system - including atmospheric pressure.






6. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






7. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






8. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






9. The square root of the variance.






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






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






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






13. The amount or quantity of something






14. 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.






15. The collection - evaluation - and interpretation of data






16. The type of charge an atomic particle has






17. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

18. The pressure exerted by the weight of the atmosphere above the point of measurement.






19. The contact of a relay that is closed when the coil is de- energized.






20. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






22. A system that links electricity produced in power stations to deliver it to where it is needed






23. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






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






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






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






27. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






28. The rotating member of an electrical machine






29. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






30. Energy derived from sources that do not use up natural resources or harm the environment






31. Categorical data graph






32. A law that states all natural processes proceed in a preferred direction






33. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






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






35. Anything for which a person is legally bound or responsible






36. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






38. A dynamo or similar machine for converting mechanical energy into electricity






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






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






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






42. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






43. A device used to remove contamination from a fluid






44. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






45. 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






46. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






47. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






48. Not having fixed limits; unrestricted; broad






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






50. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
