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. Categorical data graph percentage






2. A statsitical measurement of variability






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






4. The collection - evaluation - and interpretation of data






5. Distance between adjacent threads in a screw.






6. A switch that can provide variable motion control






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






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






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






10. 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.






11. The probability of satisfactory operation of the product in a given environment over a specified time interval.






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






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






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






15. The type of charge an atomic particle has






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






17. 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.






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






19. The geometric center of an area.






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






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






22. A set of all possible outcomes or events in an experiment that cannot be further broken down.






23. Impeding effect exerted by one material object on another.






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






25. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






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






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






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






29. 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.






30. The use of a fluid (liquid or gas) to transmit power from one location to another.






31. A device used to remove contamination from a fluid






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






33. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






34. 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






35. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






36. 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






37. The ratio of actual strength to required strength






38. A surface or shape exposed by making a straight cut through something at right angles to the axis.






39. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

40. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






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






42. A control system that considers the output of a system and makes adjustments based on that output.






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






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






45. A form of energy that travels through space as waves.






46. 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.






47. The absolute value of a number






48. Values that possess names or labels






49. A person or group for which product or service design efforts are intended.






50. 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.
