In a slope-deflection method analysis, we will typically make the assumption that all frame members are axially rigid for the purpose of determining the number of degrees of freedom in the system (i.e. Although three DOFs are possible for each node, individual directions may be considered to be restrained, either by a support reaction or by one of the members connected to the node. Usually, we consider the horizontal and vertical axes as the two perpendicular translational degrees-of-freedom. In a 2D system, each node has three possible degrees-of-freedom: translation (movement) in one direction, translation in another direction perpendicular to the first one, and rotation. This concept was previously briefly introduced in Section 1.5. Although the elements have deformations between the nodes, we can, using structural analysis methods, characterize the behaviour and deformation of the structure based on the deformations at the nodes alone.Ī degree-of-freedom (or DOF) represents a single direction that a node is permitted to move or rotate. When doing structural analysis, we often conceptualize a real structure as a simplified stick model with elements connected to each other at specific locations called nodes.

Here you can find the meaning of For a pure substance, the degree of freedom forsaturated vapour and superheated vapour area)1 and 2b)1 and 1c)2 and 1d)2 and 2Correct answer is option 'A'. In conclusion, the correct answer to the given question is option A, which states that the degree of freedom for saturated vapor and superheated vapor of a pure substance is 1 and 2, respectively. Therefore, the degree of freedom for superheated vapor of a pure substance is 1. For superheated vapor, there is only one phase present (P = 1). The degree of freedom for superheated vapor can be determined as follows: Superheated vapor can be defined as the vapor at a temperature higher than its saturation temperature corresponding to its pressure. Therefore, the degree of freedom for saturated vapor of a pure substance is 2. For saturated vapor, there is only one phase present (P = 1). For a pure substance, the number of components is one (C = 1). The degree of freedom for saturated vapor can be determined as follows: Saturated vapor can be defined as the vapor at the saturation temperature corresponding to its pressure. Where F is the degree of freedom, C is the number of components in the system, and P is the number of phases in the system. For a pure substance, the degree of freedom can be determined using the Gibbs phase rule, which is given by: The degree of freedom for a pure substance can be defined as the number of independent intensive variables that can be varied without changing the number of phases in the system.
