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 resource that can be replaced when needed






2. 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.






3. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






4. A vector quantity that includes the speed and direction of an object.






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






6. A device for making - breaking - or changing the connections in an electrical circuit.






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






8. A support that prevents translation in any direction

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






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






12. A part or element of a larger whole






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






14. 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.






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






16. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






17. 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.






18. The distance the fluid travels through a system in a given period of time.






19. Used to start and stop flow in a circuit






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






21. 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






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






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






24. The rate of change of velocity with respect to time.






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






26. 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.






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






28. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






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






30. The fractional increase in a material's length due to stress in tension or thermal expansion






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






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






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






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






35. Energy caused by the movement of electrons.






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






37. A support that prevents translation and rotation in a beam.






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






39. 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.






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






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