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.
