When a 'beam' experiences a bending moment it will change its shape and internal stresses (forces) will be developed. The photograph illustrates the shape change of elements of a beam in bending. Note ...

In a straight beam having either a constant cross section or a cross section which changes gradually along the length of the beam, the neutral surface is defined as the longitudinal surface of zero ...

The mast of a ship, the pole of a sign post, the frame of a car, the bulkheads in an aircraft, and the plank of a seesaw are among the countless examples of beams. In most cases the bending loads are ...
