The cross section of a composite beam that consists of 4-mm-thick fiberglass faces bonded to a 20-mm- thick particleboard core is shown in Figure P8.43. The beam is subjected to a bending moment of 55 N-m acting about the z axis. The elastic moduli for the fiberglass and the particleboard are 30 GPa and 10 GPa, respectively. Determine (a) the maximum bending stresses in the fiberglass faces and the particleboard core. (b) the stress in the fiberglass at the joint where the two materials are bonded together. 4 mm FIGURE P8.43 50 mm 20 mm 4 mm
