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 stress of the joint are 1.26 MPa in tension and 1.50 MPA in shear and that P= 6kN, determine the factor of safety for the joint when theta = 35 degree, also determine whether the joint will fail in tension or in shear if P is increased until rupture occurs.
two forces applied as shown to a hook support. knowing that the magnitude of P is 35 N, determine by trigonometry the required angle if the resultant R of the two forces applied to the support is to be horizontal and the corresponding magnitude of..
