A compound tube consists of a copper tube 160 mm external diameter and 140 mm internal diameter is enclosed inside a steel tube of 180 mm external diameter and 160 mm internal diameter as shown. If the compound tube carries an axial load of 900 kN, find the stresses developed and the deformation in each tube. Take E=2 x 10 N/mm and Ecu=1 x 10 N/mm Steel tube 1400 mm 180 mm 900 kN 140 mm 160 mm Copper tube 5A. A bar is composed of two segments as shown in figure. Find the stress developed in each material when the temperature is raised by 60°C when the supports are perfectly rigid. Take E=200 GPa, Ecu=100 GPa, αs=12 x 10-6/°C, αcu=18 x 10-6/°C. Acu=500 mm2 As=250 mm2 5B. Steel Copper 200 mm 250 mm A rail track is to be constructed using steel rails of 20 m long. What minimum expansion gap is to be provided so that thermal stresses in rails should not exceed 70 N/mm when the rails experience maximum rise in temperature of 40°C during peak hours? Given α=15 x 10-6/°C and E=210 GPa.

2. The stabilization energy of a type II superconductor with $N$ vortices is given by $\Delta G = G^N(H, T) - G^0(H, T) = \frac{1}{\mu_0} \int_V \nabla(\vec{r}) \cdot \left[\frac{1}{2} \vec{B} + \frac{1}{2} \vec{B}_2 - \mu_0 \vec{H} \right] dV$ where $V(\vec{r}) = \sum_{p=1}^N \Phi_0 \delta(\vec{r} - \vec{r}_p) \hat{z}$ is the vorticity. At one stage in the derivation of this equation, one ends up with the relation $\Delta G = \frac{1}{\mu_0} \int_V \nabla(\vec{r}) \cdot \left[\frac{1}{2} \vec{B} + \frac{1}{2} \vec{B}_2 - \mu_0 \vec{H} \right] dV - \frac{\chi^2}{2\mu_0} \int_S \vec{B} \times (\nabla \times \vec{B}) \cdot d\vec{S}$ where the total field $\vec{B} = \vec{B}_1 + \vec{B}_2$. Complete the proof by showing that the surface integral can be rewritten as $\frac{\chi^2}{2\mu_0} \int_S \vec{B} \times (\nabla \times \vec{B}) \cdot d\vec{S} = -\frac{1}{2\mu_0} \int_V \nabla(\vec{r}) \cdot \vec{B} dV$ Gauss theorem $\int_V \nabla \cdot \vec{C} dV = \int_S \vec{C} \cdot d\vec{S}$ and vector relations are useful in the proof.
