8. Both ends of a beam of length L is embedded at two walls and a varying load w(x) per
unit length is acting on the beam as shown in Figure 1. If y(x) be the static deflection
of the beam due to the acting load w(r), the phenomena is modeled by using a fourth
order differential equation
= w(z),

where E is the Young's modulus of elasticity and I is the moment of inertia of cross
section of the beam. Using the Laplace transform find out the the deflection y(x) of the
beam.
