This lesson gives a brief outline of how we can solve a 3bar truss problem. Considerations that should be made while solving the same are also discussed. Importance of drawing displacement diagram at nodes is very helpful in understanding the displacements. Tricks for remembering 4x4 stiffness matrix is provided in this lesson. Applying boundary conditions and reducing the finite element equation is importantly defined here. Significance of numbering each row and column of local stiffness matrix before assembling them to form global stiffness matrix is defined elaborately in this lesson. Stress determination at nodal points is also described along with the help of proper finite element equations. Assuming the outer coefficient of stiffness matrix nearly equal for different local stiffness matrix and the relevance of doing so is discussed along in this lesson.
