Stresses in Beams (Advanced Topics)
Composite Beams
When solving the problems for Section 6.2, assume that the component parts of the beams are securely bonded by adhesives or connected by fasteners. Also, be sure to use the general theory for composite beams described in Sect. 6.2. Problem 6.2-1 A composite beam consisting of fiberglass faces and a core of particle board has the cross section shown in the figure. The width of the beam is 2.0 in., the thickness of the faces is 0.10 in., and the thickness of the core is 0.50 in. The beam is subjected to a bending moment of 250 lb-in. acting about the z axis. Find the maximum bending stresses face and core in the faces and the core, respectively, if their respective moduli of elasticity are 4 106 psi and 1.5 106 psi.
y 0.10 in. z C 2.0 in. 0.50 in. 0.10 in.
