some value P, and the final deflection in the direction of the load is A, the load does work U, =PA on the structure. By conservation of energy, this work is stored in the elastic deformation energy of the structure, U¡ . For a truss, the internal strain energy is the sum of the axial strain energies in all the elements. This gives the equation N²L PA =E 2AE where N is the internal axial force in each member.
