Roebling's sister Friederike Amalie married Carl August Meissner, a poor merchant in the town, and his oldest brother Herman Christian Roebling prepared to take over the tobacco shop.

Roebling devised "an equilibrium strength approach, in which equilibrium is always satisfied but compatibility of deformations is not enforced." This was essentially an approximation method similar to the force method: First, Roebling computed the dead and live loads, then divided the load between
