2. A beam of length L is embedded in concrete walls. If a constant load W is distributed evenly along its length, the beam takes the shape of the deflection curve W WL WL y 24E1 12EI 24E1 where E and I are constants which depend on the material of the beam and the shape of its cross section. Sketch the graph of the deflection curve including all the details. Where does the maximum deflection occur, and what is its magnitude?
