Question

The formulae to find the Number of displacements for truss having 3 nodes is…………​

Answer 1

Nodes will have nodal (vector) displacements or degrees of freedom which may include translations, rotations, and for special applications, higher order derivatives of displacements. When the nodes displace, they will drag the elements along in a certain manner dictated by the element formulation.

Answer 2

Answer: The formulae to find the Number of displacements for truss having 3 nodes is F-K.

Where F is Force vector of n rows

n is degree of freedom

K is the Stiffness matrix

After you have adjusted both the stiffness matrix and the force vector you can easily solve the linear system of equations using Gaussian elimination, Cholesky decomposition etc.

Explanation:

• Nodes will have nodal (vector) displacements or degrees of freedom, which may include translations, rotations, and for certain applications, higher order derivatives of displacements.
• These nodal displacements and degrees of freedom will be associated with the nodes themselves.
• When the nodes move, they will drag the elements along with them in a specific way that is determined by the formulation of the elements.
