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. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






2. Plant materials and animal waste used especially as a source of fuel.






3. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






4. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

5. The reason for which something is done or for which something exists.






6. The use of quality control techniques associated with a process.

9. Change in length of an object in some direction per unit






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






11. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






12. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






13. Frequency distribution graph






14. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






15. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






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






17. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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






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






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






21. Any device that controls - either automatically or manually - the flow of a fluid.






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






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






24. The measure of resistance to heat flow






25. A body subjected to a push.






26. The total pressure exerted on a system - including atmospheric pressure.






27. The state when objects are not yet in motion






28. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






29. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






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






31. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






33. A straight line that comes closest to the points on a scatter plot






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






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






36. 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






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






38. 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






39. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






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






41. 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






42. A device used to convert fluid power into mechanical power in the form of linear motion.






43. Distance between adjacent threads in a screw.






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

49. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






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