Abstract The aim of the present study is to provide Physics and Engineering students with two paths regarding problem solving and non-physics students with a more intuitive solving strategy and easier to memorize in the long term. To achieve this goal, the same problem is approached in two different ways: one, formal and the other, conceptual. The problem is the compound Atwood machine with four bodies. The formal approach focuses on obtaining the equations of motion using Newton's second law, stresses the role of geometric constraints and uses an algebraic computation software. The conceptual approach consists of a knowledge transfer from the simple Atwood machine problem. In this case, the thinking process for solving the compound machine problem is the same as for the simple one but it is applied more than once. The same goes for the use made of the Gauss principle, as it was understood in the 19th century. A numerical example will show that all approaches lead to the same result.
