The principal stress at a point in a strained material are 126MPa tensile

Question

and 63 MPa 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.

Answer 1

Good
