3. Balancing Theory
A construction of building which is loaded by forces and foots tooled , so that reaction forces can be determined by balancing requires, so the construction of the building is called certain satic.

4. Balancing Theory
A construction of building which is foots tooled likewise , so that the amount of the reaction n is more than the amount of the balancing equation, so the construction of the building is uncertain static.
