Deflection of Cantilever Beam Arrangement

phiska

If two cantilever beams are fixed at Left Hand Side (LHS) and joined to eachother by means of a prop at RHS, how do i calculate the downwards vertical deflection of the bottom beam?

The beams are of length L, the prop length a.
There is a point force on the bottom beam of magnitude W, downwards, at L/2 m.

I already have calculated the downwards vertical deflection of the top beam to be (d of top)= (PL^3)/(3EI)
Where P= load in prop
EI=constant
Please see attached for diagram
