Deflection calculations

    Hi to all.

    I need to calculate the deflection at D. At point D, there is a force of 245N acting on it. If I know the cross sectional areas of all beams, is it possible to use energy method to calculate the deflection?

    Probably the best thing to do is to take a FBD of the horizontal beam and use Castigliano's method (which is related to the strain energy) to get the deflection at the load P acting at point D.
