Determine the increase in the diameter of the pressure vessel in Prob. 10€“53 if the pistons are replaced by walls connected to the ends of the vessel.

Problem: 10-53

Air is pumped into the steel thin-walled pressure vessel at C. If the ends of the vessel are closed using two pistons connected by a rod AB, determine the increase in the diameter of the pressure vessel when the internal gage pressure is 5 MPa. Also, what is the tensile stress in rod AB if it has a diameter of 100 mm? The inner radius of the vessel is 400 mm, and its thickness is 10 mm. E_st = 200 GPa and ν_st = 0.3.
