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 use of a fluid (liquid or gas) to transmit power from one location to another.






2. 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.






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






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






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






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

19. Ratio of distance traveled by the applied effort and resistance force within a system.






20. A device used to spray an oil mist into the stream of a pneumatic system.






21. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






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






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






24. 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






25. Maximum stress that a material will withstand without permanent deformation






26. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

27. The opposition that a device or material offers to the flow of direct current






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






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






30. The contact of a relay that is open when the coil is de- energized






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






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
