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. Amount of difference between a value and the mean.






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






3. The distance the fluid travels through a system in a given period of time.






4. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






5. A statsitical measurement of variability






6. A truss composed of triangles - which will retain its shape even when removed from supports.






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

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






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






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






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






16. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant


17. The ratio of actual strength to required strength






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






19. The measure of resistance to heat flow






20. An activity with observable results






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






22. Test methods used to examine an object - material - or system without impairing its future usefulness






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






24. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






25. A physical quantity that has magnitude only.






26. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






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






28. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






29. Any alteration of shape or dimensions of a body caused by stresses - thermal expansion or contraction - chemical or metallurgical transformations - or shrinkage and expansions due to moisture change






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






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






32. A resource that cannot be replaced once used






33. Bell- shaped probability distribution






34. A systemized body of laws; a set of principles - as of ethics

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






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






41. The collection - evaluation - and interpretation of data






42. 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.






43. A body subjected to a push.






44. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other
