Two wooden planks each in thick and 1 / 2 in. thick and 9 in. wide, are joined by the dry mortise joint shown. knowing that the wood used shears off along its grain when the average shearing stress reaches 1.20 ksi, determine the magnitude p of the axial load that will cause the joint to fail. two wooden members of uniform rectangular cross section of sides a = 100 mm and b = 60 mm are joined by a simple glued joint as shown. knowing that the ultimate stresses for the joint are sigma u = 1.26 mpa in tension and tau u = 1.50 mpa in shear and that p = 6 kn, determine the factor of safety for the joint when (a) alpha = 20degree, (b) 35degree, (c) alpha = 45degree. for each of these values of alpha, also determine whether the joint will fail in tension or in shear if p is increased until rupture occurs.
