A cylinder made of copper, 8.0 cm in length and 3.0 cm in radius, is firmly inserted into a rig
structure at 20°C. The thermal stress at that temperature is zero. Then, the temperature of the cylinder is raised
but not that of the structure. Discuss whether the cylinder will break, and determine the temperature at which
it will occur. Data for copper: coefficient of linear expansion 19-10-* K-; Young modulus 110 GPa; fraction
stress 230 MPa; melting point 1083°C.
