A point within an elastic body was subjected to a system of planestress. strain gauges were used to measure that would allow for thecalculation of principal strain and stress values at that point.with the given information:
The direct strain at an angle of 30o,to one of theprincipal axes was 1.34x10-3 and the corresponding shearstrain was 8.52x10-4. Calculate as many principal ormaximum strains at the point
