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






2. The result of an experiment






3. 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






4. The flow of electrical power or charge.






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






6. A valve that allows flow in one direction but prevents flow in the opposite direction.






7. The geometric center of an area.






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






9. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






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






11. A process that changes the size and shape of a material by a combination of force and a shaped form






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

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






16. 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






17. Listing of a data values along with their corresoponding frequencies.






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






19. The unit of potential difference symbolized as V






20. A statsitical measurement of variability






21. 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






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






23. A part or element of a larger whole

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






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






32. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






33. An activity with observable results






34. The process of creating an object by adding small pieces or layers together to make a final product

38. Arithmetic average






39. The basic unit of electric current adopted under the Systeme International d'Unites






40. 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.






41. Changes one form of power to another






42. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






43. A force that produces or tends to produce rotation or torsion.






44. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.

48. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






49. The probability of an event occurring based upon other event probabilities
