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. 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.






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






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






4. The unit of potential difference symbolized as V






5. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






6. An energy source that will never run out






7. Changing one form of energy to another






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






9. 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.






10. A valve that allows flow in one direction but prevents flow in the opposite direction.






11. A group of machined or handmade parts that fit together to form a self- contained unit.






12. The ratio of actual strength to required strength






13. 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.






14. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






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






16. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat






17. A system of discrete states: high or low - on or off - 1 or 0.






18. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






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






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






21. A solid- state switching device.






22. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






23. The connection points of members of a truss






24. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






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






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






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






28. The rate at which work is performed or energy is expended






29. Arithmetic average






30. The resistance that one surface or object encounters when moving over another.






31. 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.






32. A device used to remove contamination from a fluid






33. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






34. The difference between the maximum and minimum dimensions allowed within the design of a product.






35. The flow of electrical power or charge.






36. 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






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






38. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






39. 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






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






41. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






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






43. 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






44. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






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


46. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit


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






48. Categorical data graph






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






50. Categorical data graph percentage
