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. Energy caused by the movement of electrons.






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






3. 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.






4. A set of all possible outcomes or events in an experiment that cannot be further broken down.






5. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






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






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






8. The value that occurs most frequently






9. The connection points of members of a truss






10. 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






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






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






13. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






14. 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






15. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






16. A dynamo or similar machine for converting mechanical energy into electricity






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






18. A resource that cannot be replaced once used






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






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






21. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






22. A group of machined or handmade parts that fit together to form a self- contained unit.






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






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






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






26. The collection - evaluation - and interpretation of data






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






28. A device that responds to a physical stimulus






29. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






30. The measure of resistance to heat flow






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






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

33. A toothed wheel whose teeth engage the links of a chain.






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






35. A profession for which one trains and which is undertaken as a permanent calling.






36. 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






37. 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.






38. 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






39. The production of electricity in conductors with the use of magnets






40. A quantity that has both a magnitude and direction.






41. A body subjected to a push.






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






43. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.
