Expression for element forces in terms of transformation matrix and element axial forces
From the previous derivations, it was determined that the element axial force was related to the element forces in global coordinates by

$$p^{(e)}_{2x1}=T^{(e)}_{2x6}f^{(e)}_{6x1}$$

Therefore, the expression for the element forces in global coordinates in terms of the transformation matrix and the element axial forces is

$$f^{(e)}_{6x1}=T^{(e)T}_{6x2}p^{(e)}_{2x1}$$
