Truss Element Eqns Coordinate Transformation
In reality, a truss structure can be comprised of many truss members which have different orientations in the global coordinate system. Therefore, it becomes important to transform local system of equations to global coordinate system and then assemble them together.
The aim of this video is to explain coordinate transformation, also how to convert local elemental stiffness and mass matrices to global stiffness and mass matrices.
Again most of the stuff will be in the form of the equations and it will make more sense when I will discuss a few examples by applying these equations in near future.
