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 state when objects are not yet in motion






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






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






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






5. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

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






7. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






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






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






10. The magnitude of the total distance traveled divided by the time elapsed.






11. The transfer of energy by electromagnetic waves






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






13. 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






14. The connection points of members of a truss






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






16. The force per unit area exerted by a fluid against a surface






17. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






18. 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






19. An external force applied to an object.






20. 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






21. The pressure exerted by the weight of the atmosphere above the point of measurement.






22. A device used to measure flow rate.






23. 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






24. Measure of data scatter






25. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






26. The amount or quantity of something






27. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






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






29. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






30. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






31. The measure of resistance to heat flow






32. 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.






33. The stress required to fracture a material whether by compression - tension - or shear






34. 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.






35. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






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






38. The calculated likelihood that a given event will occur






39. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






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






41. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






42. Absolute temperature scale






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






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






45. The absolute value of a number






46. A resource that can be replaced when needed






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






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






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






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