The principal stress at a point in a strained material are 126MPa
tensile and 63 MP tensile, the third principal stress being zero. Find
by a circular diagram of stress the magnitude and direction of
resultant stress on a plane inclined at 300 to the direction of the
smaller principal stress and perpendicular to the plane across which
the stress is zero. Also find the maximum obliquity of the resultant
stress and its magnitude.

The magnitude of the resultant stress on the plane inclined at 30° to the direction of the smaller principal stress is 63 MPa. The maximum obliquity of the resultant stress is 60° and its magnitude is 126 MPa.
