A uniform beam of arbitrary, unsymmetrical cross$-$section and length $2l$ is built$-$in at one end and simply supported in the vertical direction at a point halfway along its length. This support, however, allows the beam to deflect freely in the horizontal x direction

i$.$ For a vertical load $W$ applied at the free end of the beam, calculate bending moments for the sections at A and $B.$

ii$.$ calculate the deflection curve as a function of the distance from Point A$.$

iii. plot the deflection curve of the beam.
