Strength of Material

A steel rod is 2m long with a diameter of 30mm has a standard temperature of 18℃. It is exposed in a room with a
temperature of 40 ℃. Use ? = 11.6 ? 10−6/℃ and E = 200 GPa. Find a.) the thermal deformation, b.) thermal stress and
c.) instead of heating the rod, what equivalent axial deformation is necessary to have a deformation that is the same as
the deformation due to the change in temperature.

A hollow circular steel column 2m long and outer diameter 200 mm carries an axial load of 325 kN. If the compressive stress is 150 MPa, lateral strain for external diameter is is 0.000325 and Poisson’s ratio is 0.3, find the minimum wall thickness required for the column. Also calculate the shear modulus for the material of the column. Take E = 210 GPa.

Due to the operational conditions and temperature gradient, a 70 mm diameter, 1.55 m long steel rod within a machine assembly is subjected to a combination of tensile loading of 150 N and thermal loading which imposes a longitudinal force of 230 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 0.5 mm in length at both ends and decreasing by 0.0125 mm at...
