* The first time a newspaper called the Academy Award an âOscarâ was in 1934, when Sidney Skolsky, a famous columnist used the word in his column on Katharine Hepburnâs first Best Actress win. * By 1939, the name âOscar,â stuck to the statuette. * The statuette weighs 8.5 lbs. and the height is 13.5 inches.
A strain gage rosette is, by definition, an arrangement of two or more closely positioned gage grids, separately oriented to measure the normal strains along different directions in the underlying surface of the test part. Rosettes are designed to perform a very practical and important function in experimental stress analysis. It can
To use g xy, the above equations should be adjusted accordingly. 2. The free surface on which the strain rosette is attached is actually in a state of plane stress, while the formulas used above are for plane strain. However, the normal direction of the free surface is indeed a principal axis for strain.Therefore, the strain transform in the free surface plane can be applied.o determine the three independent components of plane strain, three linearly independent strain measures are needed, i.e., three strain gages positioned in a rosette-like layout. a, e b, and e c, respectively. x, e y, and e xy.
