    Due to the operational conditions and temperature gradient, a 95 mm diameter, 1.75 m long steel rod within a machine assembly is subjected to a combination of tensile loading of 190 N and thermal loading which imposes a longitudinal force of 244 N. The total loading results in an even distribution of forces on the body of the rod causing it to change its dimensions by increasing 0.45 mm in length at both ends and decreasing by 0.0135 mm at...
