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 support that prevents translation in any direction






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






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






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






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






6. 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.


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






8. Information fed into a data processing system or computer.






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






10. Ratio of distance traveled by the applied effort and resistance force within a system.






11. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






12. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






13. Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance






14. Bell- shaped probability distribution






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






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






17. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






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






19. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






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






21. The return to the input of a part of the output of a machine - system - or process






22. The total length of path over which the particle travels.






23. 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.






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






25. 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.






26. Absolute temperature scale






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






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






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






30. 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.






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






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






33. A plate or bracket for strengthening an angle in framework.






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






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






36. The use of quality control techniques associated with a process.






37. 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

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






41. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






42. The use of heat from within the Earth or from the atmosphere near oceans






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






44. Arithmetic average






45. Changes one form of power to another






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






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






48. 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.






49. 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
