Experimental Stress Analysis NOTEBOOK Issue 25 - April 1995 Contents Round Apples and Other Approximations - Editorial ... Page 1 - The necessity for approximations in engineering. The Real Thing Revisited (Again) - Student Exercise ... Page 2 (An online version is also available.) - Changes in the design of aluminum alloy beverage cans have fundamentally changed the state of stress in these pressure vessels. Measurements of strain to determine the stresses in these fluted cans are made. The results are compared to those of previous experiments. (See also Issue 1 and Issue 13. ) Digital Calculus - Strain Measurement Technology ... Page 10 - The perils of integrating and differentiating digital data are discussed. The measurement data gathered for the vibration experiment in Issue 23 is used as an example. Fourier transforms are used to separate contents of the signal.
