Introduction to trusses with a brief explanation of degrees of freedom in truss element is discussed in this lesson. Truss as an assemblage of bars which are pin-jointed at corners is also defined here. x and y coordinate displacements are also discussed here. Various properties of truss stiffness matrix is discussed in this lesson. The relevance of these properties find wide application in solving or determining stiffness matrix. Definition for total and minimum potential energy is being discussed here in this video. Some of the properties of total potential energy(T.P.E) are also discussed here. Relation of equilibrium state and second order partial derivative of T.P.E is defined in this lesson. Importance and significance of square and curly bracket is also defined in this lesson. This lesson also gives a simplified derivation for trusses(3 bar).
