Based on the theory laid down in the Part 1  in this paper we are going to display applications in physics and especially in mechanics. After a short summary on coupled fields in mechanics, we generally analyze the analogies in mechanics. As the most important, the electrical analogy is discussed in details. By the electrical analogy based analytical solution we display the results of the coupled thermo-hygro problem with second sound. Finally, a few experiments are discussed, eg. experiments by electrical analogy, experiment on diffusivities, experiment on relaxation time, experiment on hydroglobe. This latter one leads to the engineering application of the problem.
