Concept of Particles and Free Body Diagram
Why FBD diagrams are used during the analysis?
It enables us to check the body for equilibrium.
By considering the FBD, we can clearly define the exact system of forces which we must use in the investigation of any constrained body.
It helps to identify the forces and ensures the correct use of equation of equilibrium.
Note:
Reactions on two contacting bodies are equal and opposite on account of Newton's III Law.
The type of reactions produced depends on the nature of contact between the bodies as well as that of the surfaces.
Sometimes it is necessary to consider internal free bodies such that the contacting surfaces lie within the given body. Such a free body needs to be analyzed when the body is deformable.
Physical Meaning of Equilibrium and its essence in Structural Application
The state of rest (in appropriate inertial frame) of a system particles and/or rigid bodies is called equilibrium.
A particle is said to be in equilibrium if it is in rest. A rigid body is said to be in equilibrium if the constituent particles contained on it are in equilibrium.
The rigid body in equilibrium means the body is stable.
Equilibrium means net force and net moment acting on the body is zero.
Essence in Structural Engineering
To find the unknown parameters such as reaction forces and moments induced by the body.
In Structural Engineering, the major problem is to identify the external reactions, internal forces and stresses on the body which are produced during the loading. For the identification of such parameters, we should assume a body in equilibrium. This assumption provides the necessary equations to determine the unknown parameters.
For the equilibrium body, the number of unknown parameters must be equal to number of available parameters provided by static equilibrium condition.
The document discusses energy methods for structural analysis, including the total potential energy method. It provides examples of deriving the strain energy stored in different structural members under different loading conditions such as axial force, bending moment, shear force, and torsion. It also provides examples of using the principle of stationary total potential energy to solve for displacements in determinate structures by assuming a displacement function and minimizing the total potential energy.
Basic Boundary Conditions in OpenFOAM v2.4Fumiya Nozaki
This document discusses different types of boundary conditions in OpenFOAM including:
1) Steady and time-varying boundary conditions such as Dirichlet, Neumann, and Robin conditions.
2) Periodic and symmetry boundary conditions that can be used for repeating geometries.
3) Mixed boundary conditions that are a weighted combination of fixed value and fixed gradient conditions, controlled by a weighting parameter.
4) Direction mixed boundary conditions for vector fields that apply different conditions in different directions using a weighting tensor.
The document discusses probability distributions and their natural parameters. It provides examples of several common distributions including the Bernoulli, multinomial, Gaussian, and gamma distributions. For each distribution, it derives the natural parameter representation and shows how to write the distribution in the form p(x|η) = h(x)g(η)exp{η^T μ(x)}. Maximum likelihood estimation for these distributions is also briefly discussed.
