The sum of their moments will be expressed at the outset as S(. + . + .)d..

https://doi.org/10.1007/978-3-658-24072-1Since the general equations presented in the preceding section are of second order, integrations which often exceed the known methods of analysis are still required. Consequently, it is necessary to use approximate methods and our formulas furnish the most tractable approach to reach this goal.
