    1. The problem statement, all variables and given/known data

    2. Relevant equations
    The answer in the book is (4F(L^3))/3EI

    3. The attempt at a solution
    I felt the above question could be simplified into a standard beam problem. I choose the following beam.

    I used the Yc equation, but when I replace a with L I get an answer of (2FL(^3))/3EI

    You seem to be ignoring the deflection of E in the y direction. That will increase the deflection at C.

    Thanks pongo38. I have taken into account the deflection at E due to F and due to Ra. this gives me 2FL(^3))/3EI.
    I then add this to the deflection at F. This gives me a total of 4FL(^3))/3EI.
