The algorithm of calculation is given. The inductive method of obtaining solutions for an arbitrary number of rods in the farm is used. The relation of the height of the truss on the length detected the value, for which the deflection increases indefinitely. Optimal truss size is found.space trussthe deflectionthe inductive methodпространственная фермапрогибиндуктивный метод
