Chapter III - Chapter 21 - Calculation of Statically Indeterminate Structures by Force Method 1. The basic requirements and key methods of this chapter are the most basic methods for calculating statically indeterminate structures. In mastering the force method, you need to grasp the following points: 1. Master the method of determining the statically indeterminate number by removing excess constraints. 2. Master the basic ideas and basic principles of the force method and the physical meaning of the force law equation. 3. Master the use of symmetry in force methods. The most important one is
