Question
A flitch beam can be fabricated by sandwiching two steel plates (2) between three wood boards (1). Dimensions for the cross section
are b- 1.1 in., d- 6.0 in., and t- 0.50 in. The elastic moduli of the wood and steel are E, - 2200 ksi and Ez - 28000 ksi, respectively.
For a bending moment of M; - +14.5 kip-ft, determine:
(a) the normal stress in each material at point H, which is located at a distance of a - 1.4 in. above the z centroidal axis.
(b) the normal strain in each material at point H.
(c) the magnitudes of the maximum bending stress in each material.
