Study the following statements. (i) The displacement method is more useful when degree of kinematic indeterminacy is greater than the degree of static indeterminacy. (ii) The displacement method is more useful when degree of kinematic indeterminacy is less than the degree of static indeterminacy. (iii) The force method is more useful when degree of static indeterminacy is greater than the degree of kinematic indeterminacy. (iv) The force method is more useful when degree of static indeterminacy is less than the degree of kinematic indeterminacy.The correct answer is

Structural analysis is the process of calculating and determining the effects of loads and internal forces on a structure, building or object. It is also a branch of solid mechanics which uses simplified models for solids like bars, beams and shells for engineering decision making.
