The work [3], where various classical theories on continuous bodies are axiomatized from the Mach-Painlevè point of view, is completed here in two alternative ways; in that work, among other things, affine inertial frames are defined within classical kinematics. Here, in Part I, a thermodynamic theory of continuous bodies, in which electrostatic phenomena are not excluded, is dealt with. The notion of gravitational equivalence among affine inertial frames and the notion of gravitational isotropy of these frames are introduced; it is shown that the isotropic inertial frames, gravitationally equivalent to a fixed frame of this kind, are those linked to this by a (possibly improper) Galilean transformation. The Euclidean physical metric on inertial spaces is consequently determined, without introducing it as a primitive notion; and this is the main completion of [3] which is obtained here.
Si completa in due maniere alternative il lavoro [3] di assiomatizzazione alla Mach Painlevé di varie teorie classiche di sistemi continui, ove, tra l'altro, riguardo alla cinematica classica si arriva a definire i riferimenti inerziali affini. Nella Parte 1 si considera una generica teoria termodinamica dei sistemi continui nella quale non si escludono fenomeni elettrostatici. Si introducono le nozioni di equivalenza gravitazionale tra riferimenti inerziali affini e di isotropia gravitazionale di tali riferimenti; si dimostra che tutti e soli i riferimenti inerziali isotropi gravitazionalmente equivalenti ad un fissato tale riferimento sono legati a questo da una trasformazione Galileiana (impropria). La metrica fisica Euclidea sugli spazi inerziali risulta quindi determinata, senza bisogno di introdurla come nozione primitiva; e ciò costituisce il principale completamento di [3] qui conseguito.
