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 recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






2. A physical quantity that has magnitude only.






3. A gear positioned between the driver and the driven gear used to change rotational direction.






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






5. 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






6. A general agreement






7. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






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






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






10. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






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






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






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






14. 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.






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






16. An electromagnetically operated switching device.






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






18. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.


19. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






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






21. 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






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






23. 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






24. A toothed wheel whose teeth engage the links of a chain.






25. A resource that can be replaced when needed






26. The place at which independent and often unrelated systems meet and act on or communicate with each other.






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






28. Information fed into a data processing system or computer.






29. A profession for which one trains and which is undertaken as a permanent calling.






30. Changing one form of energy to another






31. Arithmetic average






32. A control circuit in which the system output has no effect on the control






33. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






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






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






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






37. 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






38. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






39. The measure of resistance to heat flow






40. The geometric center of an area.






41. A support that only prevents a beam from translating in one direction.






42. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






43. 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






44. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






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






46. An energy source that will never run out






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