Each member of the truss is made from aluminium as shown in figure, Cros-sectional area are shown in the figure,
the modulus of elasticity for aluminumis E= 72 GPa. By using strain energy principle and castigliano's method determine:
i. The total strain energy of the truss for the loading shown.
ii. The vertical and horizontal displacements of point C.
