The rigid beam ABC is suspended from two steel rods as shown and is initially horizontal. The midpoint B of the beam is deflected 10 mm downward by the slow application of the force Q, after which the force is slowly removed. Knowing that the steel used for the rods is elastoplastic with E = 200 GPa and oy - 300 MPa, determine (a) the required maximum value of Q and the corresponding position of the beam, (b) the final position of the beam.

The rigid beam ABC is suspended from two steel rods as shown and is initially horizontal.
The midpoint B of the beam is deflected 10 mm downward by the slow application of the
force Q, after which the force is slowly removed. Knowing that the steel used for the rods is
elastoplastic with E = 200 GPa and oy - 300 MPa, determine (a) the required maximum
value of Q and the corresponding position of the beam, (b) the final position of the beam.
