5. Abeam is a structural member
used for bearing loads. It is
typically used for resisting vertical
loads, shear forces and bending
moments.
Beams are characterized by their
manner of
support, profile (shape of cross-
section), length, and their material.
15. In a bending beam, a point is known as a
point of contraflexure if it is a location where
bending moment is zero (changes its sign). In
a bending moment diagram, it is the point at
which the bending moment curve intersects
with the zero line.
