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 process that changes the size and shape of a material by a combination of force and a shaped form






2. 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.






3. A physical quantity that has magnitude only.






4. Degree of conformity of a measure to a standard value.






5. 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






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






7. Amount of difference between a value and the mean.






8. Measure of data scatter






9. The condition of a string - wire - or rod that is stretched between two points






10. Values that represent a measurable quantity






11. Categorical data graph






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






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






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






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






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






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






18. An activity with observable results






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






20. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






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






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






23. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






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






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






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






27. Bell- shaped probability distribution






28. A switch that can provide variable motion control






29. Pressure exerted by a confined fluid acts undiminished equally in all directions

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






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






32. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






33. The information produced by a computer






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






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






36. A subordinate routine; specifically - a sequence of computer instructions for performing a specified task that can be used repeatedly.






37. A straight line that comes closest to the points on a scatter plot






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






39. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






40. The net transfer of electric charge (electron movement along a path) per unit of time.






41. The state when objects are not yet in motion






42. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






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






44. A truss that lies in a single plane often used to support roofs and bridges






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






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






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






48. 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






49. The probability of an event occurring based upon other event probabilities
