Simply-supported beam of rectangular cross-section
Flitched beams, whose strength depended on shear connection between
parallel timbers, were used in mediaeval times, and survive today in the
form of glued-laminated construction. Such a beam, made from two
members of equal size (Fig. 2.2), will now be studied. It carries a load
w
per unit length over a span
L
, and its components are made of an elastic
material with Young's modulus
E
. The weight of the beam is neglected.
