The curved beam in Figure P9.23 is made of a steel (E = 200 GPa) that has a yield stress Y = 420 MPa. Determine the magnitude of the bending moment My required to initiate yielding in the curved beam, the angle change of the free end, and the horizontal and vertical components of the deflection of the free end.
