INFLUENCE OF THE MUTUAL GRAVITATIONAL ATTRACTION IN A SET OF MASSES OF DEADWEIGHT MACHINES

Reciprocal gravitational attraction among the masses of deadweight machines could be significant in certain conditions. A simulation with finite elements method was applied on two different types of deadweight machines: INRIM force standard machines Amsler 100 kN and Galdabini 1 MN. Results are reported in comparison with the simplified method that considers the masses concentrated on theirs barycentres.
