The horizontal beam has moment of inertia I and
elastic modulus E. The vertical bar has cross-sectional area A
and elastic modulus E. A downward force F is applied at B.
Use strain energy to determine the deflection at B.

Strategy: Draw separate free-body diagrams of the beam and
bar, and use strain energy to determine the deflection of the beam and the
change in length of the bar.
