Question

Write notes on Stoess-strain ellipsoid.

Answer 1

Hey mate,

I am here with your answer,

The earth's shape is not a sphere but an ellipsoid. Just as a sphere is based on a circle, an ellipsoid is based on an ellipse. By rotating an ellipse about one of its axes, an ellipsoid of rotation is created. It is this type of ellipsoid that most closely approximates the earth's shape.

An ellipsoid is symmetrical about three mutually perpendicular axes that intersect at the centre. ... If a, b, and c are the principal semiaxes, the general equation of such an ellipsoid is x2/a2 + y2/b2 + z2/c2 = 1.

Hope this will help you!
