Difference between degree of static and kinematic indeterminacy with example
Answers
STATIC INDETERMINACY The aim of structural analysis is to evaluate the external reactions,the deformed shape and internal stresses in the struture. If this can be accomplished by equations of equilibrium, then such structure are known as determinate structure. However,in many structure it is not possible to determine either reaction or internal stresses or both using equilibrium equation alone. A structure is said to be externally indeterminate if the number of reactions exceeds the number of equilibrium equations. KINEMATIC INDETERMINACY The joint displacements in a structure is treated as independent if each displacement (translation and rotation) can be varied arbitrarily and independently of all other displacements. The number of independent joint displacement in a structure is known as the degree of kinematic indeterminacy or the number of degree of freedom
