A beam of the cross section shown is made of a steel that is assumed to be elastoplastic with E= 200 GPa and oy= 236 MPa. The bending is about the z axis. A bending couple is applied to the beam causing plastic zones 30 mm thick to develop at the top and bottom of the beam. The couple is then removed. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

Question

Give me right solution according to the question. Urgent please 

A beam of the cross section shown is made of a steel that is assumed to be elastoplastic with E= 200 GPa and oy= 236 MPa. The bending is about the z axis. A bending couple is applied to the beam causing plastic zones 30 mm thick to develop at the top and bottom of the beam. The couple is then removed. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 90 mm - 60 mm- Determine the points where the residual stress is zero. The residual stress is zero at yo mm, mm, mm.
