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 part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






3. A type of system that uses circulating pumps and fans to collect and distribute heat.






4. The distance the fluid travels through a system in a given period of time.






5. The measurement of how difficult it is for charges to flow through a material






6. 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.






7. A device used to remove contamination from a fluid






8. A control circuit in which the system output has no effect on the control






9. 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

13. Frequency distribution graph






14. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






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






16. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






17. Pressure exerted by a confined fluid acts undiminished equally in all directions

19. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






20. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






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






22. Amount of difference between a value and the mean.






23. A device used to spray an oil mist into the stream of a pneumatic system.






24. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






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






26. A subset of a sample space






27. The difference between the maximum and minimum dimensions allowed within the design of a product.






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






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






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






31. 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.






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






33. A measure of a fluid's thickness or resistance to flow.






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






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






36. A negative temperature coefficient - also known as a thermistor - is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature.






37. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






38. 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






39. A result of a force moving an object a certain distance






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






41. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






42. Change in length of an object in some direction per unit






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






44. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






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






46. The collection and analysis of numerical data in large quantities






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






48. Conversion of a digital signal to its analog equivalent - such as a voltage.
