************** ******* ********************* ******************************* Q5. The following readings are obtained from an equiangular strain gage rosette mounted on a free and unloaded surface of a part: ao= +2000, e120 = -1000, and e240 = +1000. Gage orientation angles are measured counterclockwise, and strain values are in micrometers per meter. Determine the magnitude of the principal strains and their orientation with respect to the 0° gage. Check the results with a Mohr circle.
