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 small circuit board that controls all the processing within a computer.






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






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

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






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






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






7. The ratio of actual strength to required strength






8. Frequency distribution graph






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






10. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






11. 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.

15. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






16. Anything for which a person is legally bound or responsible






17. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






18. The amount or quantity of something






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

20. Information encoded in a digital form - which is usually stored in an assigned address of a data memory for later use by the processor.






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






22. 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






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






24. The transfer of energy by electromagnetic waves






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






26. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus

28. To monitor and control a process so that the quality of the output/product improves.






29. The absolute value of a number






30. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






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






32. The fixed point around which a lever rotates.






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






34. A type of system that uses circulating pumps and fans to collect and distribute heat.






35. A measure of how easily a material can be twisted






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

43. A system that links electricity produced in power stations to deliver it to where it is needed






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

46. A resource that can be replaced when needed






47. Energy which a body possesses by virtue of being in motion






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






49. The connection points of members of a truss
