The figure shows a beam of length L embedded in concrete walls. If a constant load W is distributed evenly along its length, the beam takes the shape of the deflection curve where E and are positive constants. (E is Young€™s modulus of elasticity and is the moment of inertia of a cross-section of the beam.) Sketch the graph of the deflection curve.
