1.43 Two wooden members shown, which support a 3.6-kip load, are joined by plywood splices fully glued on the surfaces in contact. The ultimate shearing stress in the glue is 360 psi and the clearance between the members is in. Determine the required length L of each splice if a factor of safety of 2.75 is to be achieved. 3.6 kips 5.0 in. 3.6 kips Fig. P1.43
