Solve Prob. 2.113, assuming that the magnitude of the force Q applied at B is gradually increased from zero to 260 kN and then decreased back to zero. Knowing that α = 0.640 m, determine

(a) the residual stress in each link,

(b) the final deflection of point B. Assume that the links are braced so that they can carry compressive forces without buckling

Prob. 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 σY 5 250 MPa. The magnitude of the force Q applied at B is gradually increased from zero to 260 kN. Knowing that α = 0.640 m, determine

(a) the value of the normal stress in each link,

(b) the maximum deflection of point B.
