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. Distance between adjacent threads in a screw.






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






3. 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.

5. 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.






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






7. The state when objects are not yet in motion






8. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






9. The use of gas flowing under pressure to transmit power from one location to another.






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






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






12. The condition or quality of being true - correct - or exact; precision; exactness.






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






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






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






16. The calculated likelihood that a given event will occur






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






18. The square root of the variance.






19. Bell- shaped probability distribution






20. Information encoded in a digital form - which is usually stored in an assigned address of a data memory for later use by the processor.






21. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






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






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






24. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






25. 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






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






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






28. An energy source that will never run out






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






30. The measure of resistance to heat flow






31. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






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






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






34. Changing one form of energy to another






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






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






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






38. 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.






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






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






41. A support that prevents translation in any direction






42. 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.






43. 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.






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






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






46. A device used to create flow in a hydraulic system.






47. The resultant of a system of force is the vector sum of all forces.






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






49. A switch that can provide variable motion control






50. Used to control which path fluid takes in a circuit.
