1.7 m 1 m D B 2.64 m E PROBLEM 2.113 The rigid bar ABC is supported by two links, AD and BE, of uniform 37.5 x 6-mm rectangular cross section and made of a mild steel that is assumed to be elastoplastic with E=200 GPa and = 250 MPa. The magnitude of the force Q applied at B is gradually increased from zero to 260 kN. Knowing that a = 0.640 m, determine (a) the value of the normal stress in each link, (b) the maximum deflection of point B.
