2.6 A composite rod consists of two different materials, A and B, each of length 0.5L. T1 T2 T₁<T₂ A B 0.5 L L The thermal conductivity of Material A is half that of Material B, that is, kA=2kB Sketch the steady-state temperature and heat flux distributions, T(x) and q respectively. Assume constant properties and no inter- nal heat generation in either material.
