Question No. 8
Consider the following statements – In the stiffness method of analysis
1. Statically indeterminate structures alone are considered
2. Both statically determinate and indeterminate structures can be considered
3. It is necessary to identify the redundant
4. The displacement are considered as the unknowns
5. To calculate the displacement and establish the equations of equilibrium, it will be
convenient to develop the stiffness matrix for the structure. Which of these statements are correct ?​

Answer 1

Answer:

For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature. The reactants changes into ions when dissolved in water and there is an exchange of ions in solution.
