Curved Beams
Curved Beam
Due to curvature of the beam, normal strain does not vary
linearly with depth as in the case of a straight beam.
Therefore NA will not pass through the centroid. T

State of Stress: 3D
If we know the stresses on any 3 mutually perpendicular planes through a point, then we can
determine the stresses on any inclined plane
through the same point

Mohrs Circle
Mohrs circle is a graphical method for solving
stresses, strains, moments of inertia, on
arbitrary planes.
It is an alternate method to the
