3. Consider two 2"x4" boards that are 122" long and glued together to form one 122" long beam. In case 1 they are glued together lengthwise along the wide sides while in case 2 they are glued along the narrow sides. If the ends are placed on 2 sawhorses 10' apart determine the maximum downward force in the center each could support. The glued surface in each case is parallel to the ground. Use 200 psi for the allowable glue shear stress and also use the actual dimensions of 2"x4" lumber. Also find the maximum bending stress for each case.
