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 surface or shape exposed by making a straight cut through something at right angles to the axis.






2. Frequency distibution graph






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






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






5. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.


6. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






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






8. 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






9. The law stating that the stress of a solid is directly proportional to the strain applied to it


10. The total length of path over which the particle travels.






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






12. Individual fuel cells that are combined in series.






13. Graphical representation of a material's mechanical properties






14. 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.


15. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






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






17. A device used to remove contamination from a fluid






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


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






20. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






21. The measure of resistance to heat flow






22. 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.






23. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






24. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






25. A body subjected to a push.






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






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






28. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






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






30. 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






31. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






32. A system of discrete states: high or low - on or off - 1 or 0.






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






34. A support that prevents translation and rotation in a beam.






35. Used to start and stop flow in a circuit






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






37. Conversion of an analog signal to a digital quantity such as binary.






38. A law that states all natural processes proceed in a preferred direction






39. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






40. 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






41. Used to transport fluid in a circuit






42. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






43. The absolute value of a number






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