Cоnsider а 1-m length оf аn unlоаded cylinder at a location in the cylinder some distance from the ends. The long closed cylinder is made of a steel for which E = 200 GPa and ν = 0.28. It has an internal radius a = 85 mm and an external radius b = 240 mm. What is the change in length of this portion of the cylinder after p1 = 65 MPa is applied?
