Find the dimensionless equation and suggest an expression

Question

A fixed - fixed beam is subjected to a load q (N/m) that is distributed uniformly along the beam. The governing equation for deflection y at x from one end of the beam is given by

where E , I , and No denote Young ' s modulus (N/m²), the moment of inertia of the beam (m⁴), and the tension (N) acting along the beam, respectively. Find the dimensionless equation and suggest an expression for the solution in dimensionless form.
