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. 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






2. Information fed into a data processing system or computer.






3. A device that responds to a physical stimulus






4. The absolute value of a number






5. Arithmetic average






6. A statsitical measurement of variability






7. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






8. The ratio of actual strength to required strength






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






10. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






11. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






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






13. 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






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






15. A device used to measure flow rate.






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






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






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






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






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






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






22. Slender straight pieces of a truss connected by joints.






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






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






25. A support that prevents translation in any direction






26. Bell- shaped probability distribution






27. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






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






29. The collection - evaluation - and interpretation of data






30. Measure of data scatter






31. The magnitude of the total distance traveled divided by the time elapsed.






32. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






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






34. 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






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






36. The square root of the variance.






37. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






38. 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






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






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






41. An activity with observable results






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






43. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






44. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






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






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






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






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






49. The pressure exerted by the weight of the atmosphere above the point of measurement.






50. 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.
