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 device used to remove contamination from a fluid






2. The condition or quality of being true - correct - or exact; precision; exactness.






3. The process of creating an object by adding small pieces or layers together to make a final product






4. 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






5. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






6. A body subjected to a push.






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






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






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






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






11. Listing of a data values along with their corresoponding frequencies.






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






13. 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.






14. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






15. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






16. The volume of fluid that moves through a system in a given period of time.






17. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






18. An electromagnetically operated switching device.






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






20. Middle value of a set of values arranged in order of magnitude.






21. Categorical data graph






22. The value that occurs most frequently






23. 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.






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






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






26. The use of a liquid flowing under pressure to transmit power from one location to another






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






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






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






30. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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






32. 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






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






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






35. The square root of the variance.






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






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






38. 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






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






40. Not having fixed limits; unrestricted; broad






41. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






42. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






43. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






45. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






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






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






49. The reason for which something is done or for which something exists.






50. A solid- state switching device.
