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 ratio of the magnitude of the resistance and effort forces applied a system.






2. Energy caused by the movement of electrons.






3. 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.






4. Degree of conformity of a measure to a standard value.






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






6. A truss that lies in a single plane often used to support roofs and bridges






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






8. 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






9. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






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






11. Changing one form of energy to another






12. 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






13. The use of heat from within the Earth or from the atmosphere near oceans






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. 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






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






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






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






19. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






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






21. 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






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

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






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






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






26. The difference between samples






27. 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






28. A small circuit board that controls all the processing within a computer.






29. Categorical data graph






30. The contact of a relay that is closed when the coil is de- energized.






31. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






32. A person or group for which product or service design efforts are intended.






33. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






34. A device used to measure flow rate.






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






36. The condition of a string - wire - or rod that is stretched between two points






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






38. The flow of electrical power or charge.






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






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






41. The result of an experiment






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






43. An electromagnetically operated switching device.






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






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






46. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






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






48. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






49. A tool for systematically ranking alternatives according to a set of criteria






50. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant
