Let us consider a system of material points \(P_{1} ,P_{2} , \ldots \quad ,P_{n}\) (see Fig. 5.1) having the position vectors \(\overline{r}_{1} ,\overline{r}_{2} , \ldots \quad \overline{r}_{n}\) and weight respectively \(G_{1} ,\,G_{2} ,\, \ldots \quad ,\,G_{n}\) . The weights forming a system of parallel forces, the resultant \(G = G_{1} + G_{2} + \ldots \quad + G_{n}\) can be applied in the center of the parallel forces whose position vector is given by the relation [1–6].

摘要

Let us consider a system of material points \(P_{1} ,P_{2} , \ldots \quad ,P_{n}\) (see Fig. 5.1) having the position vectors \(\overline{r}_{1} ,\overline{r}_{2} , \ldots \quad \overline{r}_{n}\) and weight respectively \(G_{1} ,\,G_{2} ,\, \ldots \quad ,\,G_{n}\) . The weights forming a system of parallel forces, the resultant \(G = G_{1} + G_{2} + \ldots \quad + G_{n}\) can be applied in the center of the parallel forces whose position vector is given by the relation [1–6].
