2.2.5 Beam Deflection

There are several methods for determining beam deflections: (i) moment area method, (ii) conjugate-beam method, (iii) virtual work, and (iv) Castigliano's second theorem, among others.

The elastic curve of a member is the shape the neutral axis takes when the member deflects under a load. The inverse of the radius of curvature at any point of this curve is obtained as
