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 body subjected to a push.






2. 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.

3. A statsitical measurement of variability

5. The collection and analysis of numerical data in large quantities






6. The resistance that one surface or object encounters when moving over another.






7. The amount or quantity of something






8. Any device that controls - either automatically or manually - the flow of a fluid.






9. The resultant of a system of force is the vector sum of all forces.






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






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






12. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






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






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






15. 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.






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






17. Slender straight pieces of a truss connected by joints.






18. Not having fixed limits; unrestricted; broad






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






20. Maximum stress that a material will withstand without permanent deformation






21. The law stating that the stress of a solid is directly proportional to the strain applied to it

22. Change in length of an object in some direction per unit






23. The flow of electrical power or charge.






24. 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.






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






26. A body subjected to pull.






27. Values that possess names or labels






28. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






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






30. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






31. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






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






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






34. The condition of unrestrained motion in a gravitational field.






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






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






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






38. The rotating member of an electrical machine






39. Energy caused by the movement of electrons.






40. A resource that cannot be replaced once used






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






42. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






43. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






44. Frequency distibution graph






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






46. A type of system that uses circulating pumps and fans to collect and distribute heat.






47. A quantity that has both a magnitude and direction.






48. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






49. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.
