Problem 2 B P = 10kN P 12 mm 25 mm Figure 1.46 2d Figure 1.47 A B Two portions of a member AB are glued along a plane making an angle a with the horizontal as shown in Fig. 1.46. The ultimate stress of glued joint is ou = 17 MPa and tu = 9MPa. Determine the range of values of angle a, for which the FOS of the member is at least equal to three. A circular bar ABC, shown in Fig. 1.47, is subjected to an axial compressive force P. Show that the displacement of the point B is one-third the vertical displacement of point A.
