A composite section 2 m in length, consisting of a steel tube with outer diameter 24 mm and thickness 3 mm, encloses a solid copper bar 18 mm diameter. An axial compressive load of 250 KN is applied on the assembly. Young’s modulus for steel and copper are taken as 2 x 105 N/mm2 and 1 x 105 N/mm2 respectively. Calculate the stresses developed in steel and copper. Also calculate the load taken by both the materials.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
